Description
The ST2329B device is a 2-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. Externally applied voltages, V

The ST2329B device accepts V

1. When OE is LOW, all I/Os are in high-impedance mode.
2. The ST2329BQTR has 2 channels. For simplicity, the diagram above shows only 1 channel.

Supplementary notes ST2329B
4.2
The ST2329BQTR may be driven by an open drain or totem pole driver and the nature of the device output is “open drain”. It must not be used to drive a pull-down resistor as the impedance of the output at HIGH state depends on the pull-up resistor placed at the I/Os.
As the device has pull-up resistors on both the I/O
VCC
and I/O
VL
ports, the user needs to ensure that the driver is able to sink the required amount of current. For example, if the settings are V
CC
= 5.5 V, V
L
= 4.3 V, and the pull-up resistor is 10 k , then the driver must be able to sink at least (5.5 V / 10 k ) + (4.3 V / 10 k ) requirements of the ST2329BQTR.
1 mA and still meet the V
IL
Load driving capability
To support the open drain system, the one-shot transistor is turned on only during high transition at the output side. When it drives a high state, after the one-shot transistor is turned off, only the pull-up resistor is able to maintain the state. In this case, the resistive load is not recommended.
In some applications where it may be required to turn off one of the power supplies powering up the level translator, the user can turn off the V
CC
(device is disabled). There is no current consumption in V
L
only when the OE pin is low
due to floating gates or other causes, and the I/Os are in a high-impedance state in this mode.

ST2329B Maximum rating
Stressing the device above the rating listed in Table 4: Absolute maximum ratings may
cause permanent damage to the device. These are stress ratings only, and operation of the device at these or any other conditions above those indicated in
Table 5: Recommended operating conditions
of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

1. Dimension b applies to the metallized terminal and is measured between 0.10 and 0.20 mm from the terminal tip. If the terminal has the optional radius on the other end of the terminal, dimension b should not be measured in that radius area.
2. Applied only for terminals.
3. Bilateral coplanarity zone applies to the exposed heatsink slug as well as the terminals.
4. Dimensions and tolerancing conform to ASME Y14.5M - 1994.
