ST2329B

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, VCC

and VL, set the logic levels on either side of the device. It utilizes a transmission gate-based

design that allows bi-directional level translation without a control pin.

The ST2329B device 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 tristate output mode which can be used to disable all I/Os.

The ST2329B device supports power-down mode when VCC is grounded/floating and the

device is disabled via the OE pin.
