DESCRIPTION/ORDERING INFORMATION

This 2-bit unidirectional translator uses two separate configurable power-supply rails. The A port is designed to

track V

CCA

. V

CCA

accepts any supply voltage from 0.9 V to 3.6 V. The B port is designed to track V

CCB

. V

CCB

accepts any supply voltage from 0.9 V to 3.6 V. This allows for low-voltage translation between 0.9-V, 1.2-V,

1.5-V, 1.8-V, 2.5-V and 3.6-V voltage nodes. For the SN74AVC2T244, when the output-enable (OE) input is

high, all outputs are placed in the high-impedance state. The SN74AVC2T244 is designed so that the OE input

circuit is referenced to V

CCA

. This device is fully specified for partial-power-down applications using Ioff. The I

off

circuitry disables the outputs, preventing damaging current backflow through the device when it is powered

down.
