DESCRIPTION/ORDERING INFORMATION

This dual-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is

designed to track V

CCA

. V

CCA

accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track

CCB

. V

CCB

accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional

translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.

SN74AVC2T245 SCES692A – JUNE 2008 – REVISED MAY 2012 www.ti.com DESCRIPTION/ORDERING INFORMATION (CONTINUED) The SN74AVC2T245 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode .
