Texas Instruments 1Q 2009

Introduction

Texas Instruments (TI) provides complete interface solutions that empower you to differentiate your products and accelerate time-to-market.

Our expertise in high-speed, mixed-signal circuits, system-on-a-chip integration and advanced product development processes ensures you will receive the silicon, support tools, software and technical documentation to create and deliver the best products on time and at competitive prices. Included in this selection guide you will find design considerations, technical overviews, graphic representation of portfolios, parametric tables and resource information on the following families of devices:

LVDS: (p. 4) TIA/EIA-644A specification designed for differential transmission delivering signaling rates into the Gbps range and power in the mW range with low EMI to the telecommunication and consumer markets.

xECL: (p. 4) Emitter coupled logic (xECL), high-speed differential interface technology designed for low jitter and skew.

CML: (p. 4) Current-mode logic (CML), high-speed differential interface technology.

M-LVDS: (p. 8) TIA/EIA-899 specification with all the benefits of LVDS applicable to multipoint bus architecture in backplanes. Used often for clock distribution, e.g., AdvancedTCA.

Digital Isolators: (p. 10) The new ISO72x highspeed digital isolators use state-of-the-art integrated capacitive coupling and silicon-dioxide isolation barrier to provide up to 150-Mbps signaling rate with only 1-ns jitter, best-of-class noise immunity and high reliability.

Industrial Serializers: (p. 11) In combination with galvanic isolators these devices complete the interface between high voltage signals on the field-side and the low-voltage signals on the controller side.

RS-485/422: (p. 12) Robust TIA/EIA-485 and

TIA/ EIA-422 specifications specially designed for harsh, industrial environments transmitting a differential signal up to 50 Mbps or 1.2 km.

RS-232: (p. 14) TIA/EIA-232 specification defining single-ended interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE).

UARTs: (p. 17) Universal Asynchronous Receiver/

Transmitters are the key logic component of serial communication utilizing RS232, RS485/422 or

LVDS transceivers to transmit or receive between remote devices performing parallel to serial conversion in the transmit process and serial to parallel conversion in the receive process.

CAN: (p. 19) Controller Area Network (ISO11898) specification commonly used in automotive and industrial applications describes differential signaling at a rate up to 1 Mbps on a 40-meter bus with multipoint topology.

FlatLink™ 3G: (p. 20) A new family of serializers and deserializers designed for mobile phone displays.

SerDes: (p. 21) Serializers and deserializers in the gigabit range designed to bridge large numbers of data bits over a small number of data lines in telecommunication applications.

DVI/PanelBus™: (p. 23) The Digital Visual

Interface Specification, DVI, is an industry standard developed by the Digital Display Working

Group (DDWG) for high-speed digital connection to digital displays. DVI uses transition-minimized

DC balanced (TMDS) data signaling.

TMDS: (p. 25) Transition minimized differential signaling is the electrical interface used by DVI and HDMI.

USB Hub Controllers and Peripheral Devices:

(p. 26) The USB standard was established to make connecting PCs, peripherals and consumer electronics flexible and easy. The hub controller manages USB port connect/disconnect activities and a peripheral controller enables USB connectivity of a peripheral device to either a host or hub.

USB Power Managers: (p. 28) TI products, like

TPS204xA and TPS205xA, are designed to meet all the USB 1.0 and 2.0 requirements for currentlimiting and power switching to reliably control the power on the voltage bus.

PCI Express

®

: (p. 30) The PCI Express architecture is a robust, scalable, flexible, and cost-effective serial I/O interconnect, enabling dedicated point-to-point connectivity between peripherals.

PCI Bridges: (p. 33) A peripheral component interconnect (PCI) bridge provides a highperformance connection path between either two

PCI buses or a PCI component and one or more

DSP devices.

Power Distribution Switches: (pp. 34-35) The

CardBus controller uses the card detect and voltage sense pins to determine a PC card’s voltage requirements and then directs the

PCMCIA power switch to enable the proper voltages. Standard PC cards require that V

CC be switched between ground, 3.3 V, and 5 V, while V

PP

is switched between ground, 3.3 V, 5 V, and 12 V. CardBay sockets have the standard requirements for V

CC and 5 V to V

PP

V

CORE

, but require ground, 3.3 V,

, and ground, 1.8 V, or 3.3 V to

. Other PC card applications may simply not

while still having the standard need 12 V or V

PP requirements for V

CC

. Therefore, consider the voltage requirements of the application when selecting a PCMCIA power switch.

1394: (p. 36) IEEE 1394 (FireWire

®

) high-speed interconnection enables simple, low-cost, highbandwidth, real-time data connectivity between computers, peripherals and consumer electronics.

ESD/EMI Protection: (p. 39) Transient voltage suppressors which protect multiple interfaces from ESD/EMI and electrical noise transients.

The majority of devices comply with the

IEC-61000-4-2 ESD protection specification.

I

C bus is useful for many of today’s microcontroller- and microprocessor-based systems or other systems linking many I/O devices.

Voltage-Level Translation : (p. 41) TI offers a full spectrum of products to achieve voltagelevel translation, including dual-supply level translators; FET switches; and devices with over-voltage tolerance, TTL-compatible inputs and open-drain outputs.

Design Considerations

Signaling Rate — TI offers repeaters/ translators and crosspoint switches with signaling rates up to 4 .0 Gbps .

Jitter — Reducing jitter, the deviation of a signal timing event from its ideal position, has become a priority for ensuring reliability in high-speed data buses .

Skew — Excessive skew, the time delta between the actual and expected arrival time of a clock signal, can limit the maximum bandwidth performance and lead to data sampling errors . Low skew specifications make high-speed interconnect devices excellent for signal buffering .

Power Consumption — Low-voltage differential signaling (LVDS) offers a low-power alternative to ECL and PECL devices . Current-mode drivers in LVDS produce a constant current, which allows power consumption to be relatively independent of frequency .

The constant current driver delivers about 3 .5 mA to a 100-Ω load .

Technical Information

• LVDS is based on the TIA/EIA-644A standard conceived to provide a generalpurpose electrical-layer specification for drivers and receivers connected in a point-to-point or multidrop interface .

Digital Isolators

Design Considerations

Reliability — Proven reliability of silicondioxide (SiO

2)

insulation; stable over temperature and moisture; life span

> 25 years .

Highest Noise Immunity — Only TI uses differential signals to cross the isolation barrier . Giving the highest immunity from external magnetic and electric fields to prevent data corruption .

Signaling Rate — TI offers digital isolators with the highest signaling rates of up to

200 Mbps . With the lowest skew and pulse distortion of only 1 ns .

Lowest Jitter — To ensure signal integrity, jitter reduction is a priority . ISO72xx products offer the lowest jitter with 1-ns jitter at 150-Mbps PRBS NRZ data input .

Low pulse skew

(pulse-width distortion)

• –40° to 125°C operation

• Low-input current requirement of 10 µA

• Fail-safe output

Technical Information

The ISO72xx is a family of digital isolators using the industry’s first application of silicon-based digital capacitive isolation technology . Digital buffers capacitively couple data signals through a dual

SiO

2

insulation barrier, which provides galvanic isolation of up to 4000 V .

The device receives digital inputs and provides clean digital outputs while preventing noise currents and/or excessive voltages from entering the local ground .

TI produces the SiO

2

insulation in TI isolation devices in semiconductor fabrication process producing a near zero defect glass insulation layer . Then the input signal crosses this isolation barrier, as a differential signal to insure the highest immunity to external noise .

All these features come together to make the longest lasting, most reliable isolation devices on the market .

Industrial Serializers

Industrial Serializers

The new industrial serializers convert eight digital inputs, ranging from 0 V to

34 V, into a single data stream on SPI interface, which simplifies the design and saves 60% overall board space for industrial automation and test and measurement equipment . The device’s adjustable input current limit allows the use of a single resistor to set the maximum input current in the range of

200 µA to 5 mA, which reduces systemlevel power dissipation by more than

50% typical industrial applications .

RS-485/422

Design Considerations

Interoperability — In general, RS-485 is a superset of RS-422 . Compliance with the TIA/EIA standard will ensure reliable data communication in a variety of networks, including Modbus, INTERBUS,

PROFIBUS, BACnet and a variety of proprietary protocols .

Robustness — RS-485 is a robust interface standard for use in industrial environments . It features a wide common mode range of –7 V to 12 V. Parts from

TI are available with ESD protection up to 30 kV .

Reliability — Integrated fail-safe circuitry protects the bus from interpreting noise as valid data when short-circuit, opencircuit or idle line fault conditions occur .

Speed and Distance — Low noise coupling of differential signaling with twisted-pair cabling and wide common-mode voltage range allows data exchange at signaling rates of up to 50 Mbps or to distances of several kilometers at lower rates .

Line Loading — RS-422 is capable of supporting one driver and up to 10 receivers on the bus line . Standard

RS-485 is capable of supporting up to

32 unit loads or nodes on the bus line .

However, there are reduced unit load devices available that can support up to

256 devices .

Termination — A multipoint bus architecture requires termination at both ends of the bus line . The termination resistors must be within 20 percent of the characteristic impedance of the cable and can vary from 90 W to 120 W .

Technical Information

• The main difference between RS-422 and RS-485 is the multidrop and multipoint bus architecture—that is, one driver to many receivers and many drivers to many receivers, respectively .

• Typical signaling rates and distances for these standards are up to 10 Mbps or up to 1 .2 km . TI offers devices capable of reaching signaling rates of up to 50 Mbps .

UARTs (Universal Asynchronous Receiver/Transmitters)

Design Considerations

The UART is a key component of an asynchronous serial communications system . For example, all internal modems have their own UARTs . In this application, parallel data within the computer is converted by the UART to serial data before being transferred to the modem . In addition to PC/peripheral communication, UARTs can be used for chip-to-chip communications .

As data transfer speeds have increased to support applications such as telecommunication base stations, cell phones, PCs, fax servers and rack modems, the transmission rate of the

UART has become critical to preventing system bottlenecks . When a fast external modem is used, designers should be sure the computer’s UART can handle the modem’s maximum transmission rate . For example, the TL16C550D

UART contains a 16-byte buffer, enabling it to support higher sustained transmission rates than the older 8250

UART . To reduce software buffering and data overruns, TI has added its patented hardware autoflow control to all new designs and most existing

UARTs . Most UARTs allow the divisor to be programmed from 1 to 65,535 and sometimes with an added predivisor factor of 1, 4, 16 or 64 .

To accommodate the requirements of diverse applications, TI offers a wide portfolio of parallel-to-serial and serialto-parallel UARTs in highly integrated, space-saving configurations that allow designers to increase system performance while decreasing space requirements .

As one of the world’s leading highvolume semiconductor manufacturers,

TI offers designers and OEMs the satisfaction of knowing they are backed by a supplier with the resources to meet their needs . These include a dedicated marketing and technical support team to assist with any issues .

CAN (3.3-V and 5-V High-Speed CAN Transceivers)

Design Considerations

Bus Protection — Features such as short-circuit protection, thermal shutdown protection, glitch-free powerup and power-down protection, high-

ESD protection, wide common-mode range that provides for common-mode noise rejection, and current-limiting circuitry to protect the transceivers and system from damage during a fault condition have been incorporated into these devices .

Electromagnetic Compatibility —

An important requirement for products intended for networking applications is that they behave in a way that does not interfere with the operation of other nearby components or systems . TI offers specially designed and tested transceivers for EM compatibility without malfunction or degradation of performance in rugged EM environments .

Compatibility in this definition means both immunity to external EM fields, and the limited strength of generated EM fields .

Supply Voltage — In addition to 5-V transceivers, TI offers 3 .3-V transceivers that accomplish the same tasks with less than half the power and save on the cost of an additional voltage regulator in 3 .3-V powered applications .

Technical Information

• ISO11898 specifies the physical-layer implementation of CAN .

• This specification describes a twisted wire pair bus with 120-W characteristic impedance (Zo) and differential signaling rate of up to 1 Mbps on a

40-meter bus with multi-drop topology .

Standard Compliant Protocols

CAN is a serial communications bus for robust real-time control applications that is rapidly gaining the attention of industrial process, test, measurement and control engineers worldwide . It has excellent error detection and confinement capabilities, and has the flexibility to operate either as a primary backbone data communications network, as a secondary local embedded system, or as both . The engineering community is just now exploring the limits of what this bus can do when coupled with newly developed intelligent sensing technologies .

Texas Instruments 1Q 2009

Besides CAN’s high reliability, another of the main advantages of CAN when compared to alternative networks, is the availability of higher layer protocols

(HLPs) . There are many CAN-related system development packages prepared for these HLPs – hardware interface cards and easy-to-use software packages that provide system designers with a wide range of design and diagnostic tools . These components provide for the rapid development of complex control applications without building each node of a system network from scratch .

The HLP relieves a developer from the burden of dealing with CAN-specific details such as bit-timing and implementation functions . It provides standardized communication objects for real-time data with Process Data Objects (PDOs) and Service Data Objects (SDOs), and provides special functions such as a time stamp, a sync message, and emergency shut-down procedures as well as network management, boot-up commands, and error management .

Among the most popular HLPs are

CANopen, CANkingdom and DeviceNet with applications ranging from medical equipment to process control and assembly line coordination .

TMDS (for HDMI and DVI)

Transition Minimized Differential

Signaling (TMDS) is the electrical level standard used to transmit Digital Visual

Interface (DVI) and High-Definition

Multimedia Interface (HDMI) data .

Design Considerations

Intra-Pair Skew – The time difference between the true and complementary signals of a given differential pair should be kept as small as possible .

Residual Jitter – The difference in the amount of measured jitter between the test point and the signal source . It is the allowable maximum residual jitter equivalent to the minimum jitter budget between transmitter and receiver .

TMDS

ESD – External connectors being exposed to the outside world are especially susceptible to electrostatic discharge . A higher ESD rating provides improved protection .

USB Hub Controllers and Peripheral Devices

Universal Serial Bus (USB)

The USB standard defines a bus product that requires a host controller and enables plug-and-play connectivity .

The most recently released final specification, USB 2 .0, defines high speed and allows complete backward compatibility with USB 1 .1 .

USB products fall into three categories: hubs, host controllers and peripherals .

USB 1 .1 supported speeds of up to

12 Mbps and cables up to 5 meters long for these devices . USB 2 .0 extends the connection speed to 480

Mbps to support next-generation peripherals of higher-performance PCs and applications . USB 2 .0 officially defines three speeds: low (1.5 Mbps), full (12 Mbps) and high (480 Mbps) .

The lowest speed is ideal for human interface devices such as a mouse, game pad or keyboard; while full speed is well suited for “data dumps” to the

PC via digital still cameras, PDA cradles and flash-card readers . Modems, printers, scanners and storage drives are just a few of the items that can take advantage of USB’s highest speed specification .

The USB On-The-Go (OTG) supplement to USB 2 .0 specifies a new class of devices aimed at the portable market . USB OTG defines devices that can operate as standard

USB peripherals when connected to a standard USB host controller .

However, these same devices can operate as reduced-function host controllers to support selected

USB OTG peripheral devices . Endequipment manufacturers can specify what type of peripherals their devices will support when in OTG host mode .

This new specification allows easy sharing of contact information between

USB OTG PDAs and cell phones or printing of photographs directly from an OTG-enabled digital still camera without a PC .

Technical Information

Speed

• The USB 2.0 standard defines three speeds: low speed (LS) 1.5 Mbps, full speed (FS) 12 Mbps and high speed (HS) 480 Mbps . It requires full backward and forward compatibility for devices and cables . All three modes offer both asynchronous and isochronous (real-time) data transmission over a simple and inexpensive 4-wire cable to meet requirements of peripherals including keyboards, mice, printers, speakers, scanners, external storage devices and digital still cameras .

Transfer Type

• USB 2.0 defines four types of transfers: bulk, control, interrupt and isochronous . Bulk transfer is intended for applications such as printers, scanners and mass storage, where latency isn’t critical but accuracy is . All devices must include control transfers for configuration . Interrupt transfer is for devices such as mice, keyboards and game pads that must receive the host’s or device’s attention periodically . Isochronous transfer offers guaranteed delivery time but no error-checking or automatic retransmission of data received with errors, making it the better choice for audio or video applications .

drives, while TPS2149 is for USB buspowered hubs, such as keyboards with integrated hubs . TPS2148/9 each combine a 3 .3-V LDO and dual power switch in a single MSOP package . The

TPS2148 switch configuration allows power and board capacitance segmentation to meet USB system current requirements . The TPS2149 switches manage two independent or four ganged USB ports .

4-Port USB Hub Power Controllers

TPS207x – The TPS207x family provides the complete power solution for 4-port self-powered, bus-powered or hybrid

USB hubs by incorporating current-limited switches for four ports, a 3 .3-V 100-mA

LDO, a 5-V LDO controller for self power

(TPS2070, TPS2071) and a DP0 line control to signal an attach to the host .

USB Current-Limiting Power Switches

Power switches are used to intelligently turn power on/off and provide fault protection . They are ideal for power sequencing or segmentation and when controlled allocation of power is needed to circuit blocks, modules, add-in cards or cabled connections .

Universal serial bus (USB) ports are great examples of where this intelligent protection is vital for protecting your power supply and achieving regulatory compliance . TI’s family of low-cost power switches are ideal for USB port designs .

To minimize voltage drop, select devices with the lowest r

DS(on) on-resistance .

or Drain-to-Source

Power Distribution Switches

The low-cost and low r

DS(on)

currentlimiting power switch families meet all the USB power management requirements for controlling downstream ports, and include additional features to improve the design reliability .

PCI Bridges

Design Considerations

Peripheral Component Interconnect (PCI) is an interconnection system between a microprocessor and attached devices in which expansion slots are spaced closely for high-speed operation . A PCI-to-PCI bridge is a high-performance connection path between two PCI buses that allows bridge transactions to occur concurrently on both buses . Burst-mode transfers maximize data throughput while the two bus traffic paths through the bridge act independently . In future systems, many PCI bus structures will be replaced by the new serial PCI Express architecture . TI is actively developing a portfolio of PCI Express products to address this market .

Key Features

• Two 32-bit, 33- or 66-MHz buses

• Configurable for PCI powermanagement interface specification

• CompactPCI hot-swap functionality

• 3.3-V core logic with 3.3- to 5-V PCI signaling compatibility

• Intel

CardBus Power Switches

Design Considerations

ExpressCard Power Switches

The TPS2231 and TPS2236 ExpressCard power interface switches provide the total power management solution required by the ExpressCard specification . The

TPS2231 and TPS2236 ExpressCard power interface switches distribute 3 .3 V,

AUX and 1 .5 V to the ExpressCard socket .

Each voltage rail is protected with integrated current-limiting circuitry . The

TPS2231 supports systems with singleslot ExpressCard/34 or ExpressCard/54 sockets . The TPS2236 supports systems with dual-slot ExpressCard sockets .

PCMCIA/CardBus Power Switches

Standard PC cards require that V

CC

be switched between ground, 3 .3 V and 5 V, while V

PP

is switched between ground,

3 .3 V, 5 V and 12 V . CardBay sockets have the standard requirements for

V

CC

, but require ground, 3 .3 V and 5 V to V

CC

V

, and ground, 1 .8 V or 3 .3 V to

CORE

. Other PC card applications may simply not need 12 V or V

PP

while still having the standard requirements for

V

CC

. Therefore, consider the voltage requirements of the application when selecting a PCMCIA power switch .

Power MUX ICs

Power MUX ICs are designed to transition from a main power supply to an auxiliary source when the main supply shuts down

(e .g ., switching from battery operation to a wall adapter) .

For more information on these and other switches, please see the USB current-limiting power switches on page 28.

Current-Limiting Power Switches

Power switches are used to intelligently turn power on and off, while providing fault protection . They are useful anywhere controlled allocation of power is needed to circuit blocks, modules, add-in cards or cabled connections .

They are ideal for power sequencing or segmentation .

To minimize voltage drop, select devices with the lowest r

DS(on) on-resistance .

1394 (FireWire

®

)

Overview

IEEE 1394 high-speed interconnection enables simple, low-cost, high-bandwidth real-time data connectivity between many types of electronic equipment . As a multimedia network standard, 1394 is ideally suited for consumer electronics, computers and peripherals .

It is also ideal for situations that benefit from true peer-to-peer operation and maximum flexibility . 1394 is self-configuring, has strong power management/distribution capabilities and robust error-detection that make it a leading choice in control applications, especially those that also need to accommodate streaming multimedia .

The new 1394b technology enables higher performance (STP, UTP, POF, GOF and Coax), longer distance (STP, UTP, POF, GOF and Coax) and a variety of cable media to fit any application (STP, UTP, POF, GOF and Coax), making it ideal for home networking and high-speed data transfer applications . For example, 1394b is capable of 400 Mbps over coax or unshielded twisted pair Category 5 cable (called

CAT5 or UTP5) . For high-speed applications, TI offers a 1394b chip set that enable speeds up to 800 Mbps for applications such as video-on-demand or backing up a RAID array . TI 1394b is backward compatible to 1394a .

Design Considerations

Physical-Layer Selection Issues

• The 1394 PHY layer should support the minimum number of nodes or ports required by the end product . Having two ports permits spanning to other devices on the bus through daisychaining . Three or more nodes enable branching or hub capabilities .

• The suspend/resume feature of the

PHY layer lets two currently inactive ports achieve low-power states while maintaining their connection status . It also permits them to quickly resume operation as soon as they detect an applied port bias voltage .

• Another aspect of the link layer that should be considered is the amount of data-buffer memory supported .

Typically, the more bandwidth an application requires, or the more simultaneous isochronous/ asynchronous traffic that needs to be supported, the larger the buffer memories must be .

• Will the end product need DC isolation at the 1394 interface? The cable doesn’t provide a DC-isolated path from node to node . In cases where there’s a possibility for the various equipment connected across 1394 to be at different ground potentials or different power domains, the grounds may need to be isolated from each other to prevent excessive currents and noise . However, the ground signal on the 1394 cable must not be DC-isolated from the PHY powerdistribution ground plane . Thus when

DC isolation between units is required at the 1394 interface, it is frequently performed at the PHY- and link-layer interfaces—often through the use of special I/O cells that allow for capacitive coupling of the PHY-link signals .

Link-Layer Selection Issues

• What kind of data needs to be transferred? Some link controllers are designed to implement specific data protocols over 1394, such as the serial bus protocol 2 (SBP-2) for mass storage or IEC 61883-4 for MPEG-2 transport, and some are designed as general purpose .

• What is being interfaced to 1394? If the system has PCI, consider one of the

PCI/OHCI links . Applications involving streaming compressed audio/video most likely need a link from the iceLynx family . Other TI links have interfaces for external processors/memory or are dedicated for a peripheral function

(camera/storage) .

• As the number of simultaneous isochronous channels present goes up, or the bit rate of an individual stream increases, the receive buffer needs to be larger .

• While the EIA-775 specification requires a minimum speed of 200 Mbps at the

1394 interface, using 400-Mbps PHYs is recommended . Slower nodes present on the bus can be a source of speed traps . Almost all 1394 silicon available today is already 400-Mbps capable .

Interface Guide

• For audio/visual (A/V) applications, different types of A/V data require different formatting and transmission methods on 1394 . Specifically identifying which types of A/V to be supported is fundamental to choosing the right 1394 chip set for the digital set-top box (DSTB) or digital TV (DTV) design . Standards define how to carry

MPEG-2 transport streams in both digital video broadcasting (DVB) format and in DirecTV format, which have different packetization schemes .

Technical Information

• 1394-1995 is an IEEE designation for a high-performance serial bus . A revision to this standard has been published as IEEE 1394a-2000, and clarifies and adds to portions of the IEEE 1394-1995 standard . The 1394b standard increases the speed of 1394 to 800,

1600 and 3200 Mbps, as well as providing new connection options such as plastic optical fiber (POF), glass optical fiber (GOF) and UTP-5 . This serial bus defines both a backplane

(for example, VME, FB+) physical layer and a point-to-point, cable-connected virtual bus . The backplane version operates at 12 .5, 25 or 50 Mbps, whereas the cable version supports data rates of 100, 200, 400, 800 and

1,600 Mbps across the cable medium supported in the current standard .

Both versions are totally compatible at the link layer and above . The interface standard defines transmission method, media and protocol .

Texas Instruments 1Q 2009

1394 (FireWire

Technical Information (Continued)

• Applications of the cable version are the integration of I/O connectivity of personal computers, peripherals, and consumer electronics using a low-cost, scalable, high-speed serial interface .

The 1394 standard provides services such as real-time I/O and live connect/ disconnect capability for devices including storage (HDD, CD-ROM,

CDRW, MO, ZIP, RAID, SAN, etc .), printers, scanners, cameras, set-top boxes, HDTVs and camcorders .

ESD/EMI Protection

Design Considerations

I/O Pin Capacitance – The allowable bandwidth through an ESD protection device is directly correlated to the I/O Pin

Capacitance of the protection device . TI’s portfolio offers a wide range of ESD/EMI protection devices that cover a multitude of end applications and protected ports .

I/O capacitance of our devices range from

35 pF for lower speed applications down to <1 pF for high speed applications .

Breakdown Voltage – The breakdown voltage of an ESD protection device is defined as the maximum voltage allowed to pass across the internal diodes of the monolithic circuit, prior to it breaking down and dissipating the energy safely to ground . Different applications require certain breakdown voltages, and TI’s portfolio addresses this with our broad product offering .

Voltage-Level Translation

Design Considerations

Supply voltages continue to migrate to lower nodes to support today’s low-power, high-performance applications . While some devices are capable of running at lower supply nodes, others might not have this capability . To have switching capability between these devices, the output of each driver must be compliant with the input of the receiver that it is driving .

• Provide migration paths from old architectures to new architectures

For two devices to have switching capability:

• V

OH

of the driver must be greater than the V

IH

• V

V

IL

of the receiver

of the driver must be less than the

of the receiver

• The output voltage from the driver must not exceed the I/O voltage tolerance of the receiver

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
