DESCRIPTION

The 74VCX1632245 is a dual supply low voltage

CMOS 16-BIT BUS TRANSCEIVER fabricated

with sub-micron silicon gate and five-layer metal

wiring C MOS technology. Designed for use as an

interface between a 3.3V bus and a 2.5V or 1.8V

bus in a mixed 3.3V/1.8V,3.3V/2.5V and 2.5V/

1.8V supply systems, it achieves high speed

operation while maintaining the CMOS low power

dissipation.

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

nDIR inputs. The enable inputs nG can be used to

disable the device so that the buses are effectively

n = 1, 2
