ST2329B 2-bit dual supply level translator without direction control pin, open drain output

The ST2329B 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, VCCand 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 accepts VLfrom 1.65 to 3.6 V and VCCfrom 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 ST2329B supports power-down mode when VCCis grounded/floating and the device is disabled via the OE pin
