Externally applied voltages, VCC and VL, set the logic levels on either side of the device. It utilizes a transmission gate-based design that allows bidirectional level translation without a control pin. The ST2329A accepts VL from 1.65 to 3.6 V and VCC from 1.80 to 5.5 V, making it ideal for data transfer between low-voltage ASICs/PLD and higher voltage systems. This device has a tri-state output mode which can be used to disable all I/Os. The ST2329A supports power-down mode when VCC is grounded/floating and the device is disabled via the OE pin.

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/OVCC and I/OVL ports, the user needs to ensure that the driver is able to sink the required amount of current. For example, if the settings are VCC = 5.5 V, VL = 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) = 1 mA and still meet the VIL requirements of the ST2329A. 4.2 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. 4.3 Power-off feature In some applications where it might be required to turn off one of the power supplies powering up the level translator, the user may turn off the VCC only when the OE pin is low (device is disabled). There is no current consumption in VL due to floating gates or other causes, and the I/Os are in a high impedance state in this mode. 4.4 Truth table Table 3.
