DESCRIPTION

This 16-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 1.65 V to 5.5 V. The B port is designed to track

CCB

. V

CCB

accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional

translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.

The SN74LVCH16T245 is designed so that the control pins (1DIR, 2DIR, 1OE, and 2OE) are supplied by V

CCA

SN74LVCH16T245-EP SCES726A – NOVEMBER 2008 – REVISED NOVEMBER 2013 www.ti.com DESCRIPTION (CONTINUED) The SN74LVCH16T245 is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the Aport outputs or place both output ports into the high-impedance mode.
