The DS26C31T meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The DS26C31M is compatible with EIA standard RS-422; however, one exception in test methodology is taken(2). This enables the construction of serial and terminal interfaces while maintaining minimal power consumption. 1 • • • • • TTL Input Compatible Typical Propagation Delays: 6 ns Typical Output Skew: 0.5 ns Outputs Will Not Load Line When VCC = 0 V DS26C31T Meets the Requirements of EIA Standard RS-422 Operation From Single 5-V Supply Tri-State Outputs for Connection to System Buses Low Quiescent Current Available in Surface Mount Mil-Std-883C Compliant 2 Applications Differential Line Driver for RS-422 Applications The DS26C31 accepts TTL or CMOS input levels and translates these to RS-422 output levels. This part uses special output circuitry that enables the drivers to power down without loading down the bus. This device has enable and disable circuitry common to all four drivers. The DS26C31 is pin compatible to the AM26LS31 and the DS26LS31. All inputs are protected against damage due to electrostatic discharge by diodes to VCC and ground.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information The DS26C31 is a quad differential line driver designed for applications that require long distance digital data transmission over balanced cables. The DS26C31 can be used in applications that require conversion from TTL or CMOS input levels to differential signal levels, compatible to RS-422. The use of complimentary signaling in a balanced transmission media provides good immunity in the midst of noisy environments or shifts in ground reference potential. 10.2 Typical Application Figure 28 depicts a typical implementation of the DS26C31x device in a RS-422 application. *RT is optional although highly recommended to reduce reflection. Figure 28. Two-Wire Balanced System, RS-422 10.2.1 Design Requirements • Apply TTL or LVCMOS signal to driver input lines INPUT A-D. • Transmit complementary outputs at OUTPUT A-D. • Use controlled-impedance transmission lines such as printed circuit board traces, twisted-pair wires or parallel wire cable. • Place a terminating resistor at the far end of the differential pair. 10.2.2 Detailed Design Procedure • Connect VCC and GND pins to the power and ground planes of the PCB with a 0.1-µF bypass capacitor. • Use TTL/LVCMOS logic levels at INPUT A-D. • Use controlled-impedance transmission media for the differential output signals. • Place an optional terminating resistor at the far-end of the differential pair to avoid reflection. 14 Submit Documentation Feedback Copyright © 1998–2015, Texas Instruments Incorporated Product Folder Links: DS26C31M DS26C31T DS26C31M, DS26C31T www.ti.com SNLS375C – JUNE 1998 – REVISED JANUARY 2015 Typical Application (continued) 10.2.3 Application Curves Figure 29.

A 0.1-µF bypass capacitor should be connect to the VCC pin such that the capacitor is as close as possible to the device. 12 Layout 12.1 Layout Guidelines The output differential signals of the device should be routed on one layer of the board, and clearance should be provided in order to minimize crosstalk between differential pairs that may be running in parallel over a long distance. Additionally, the differential pairs should have a controlled impedance with minimum impedance discontinuities and be terminated at the far-end, near the receiver, with a resistor that is closely matched to the differential pair impedance in order to minimize transmission line reflections. The differential pairs should be routed with uniform trace width and spacing to minimize impedance mismatching. 12.2 Layout Example Via to VCC Plane Input Via to GND Plane 16 1 Bypass Capacitor TX Differential Pair 2 15 3 14 4 13 Input TX Differential Pair Enable DS26C31M/DS26C31T TX Differential Pair Input 5 12 6 11 7 10 8 9 Enable TX Differential Pair Input Via to GND Plane Figure 31.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
