DESCRIPTION

The 74VCX163245 is a dual supply low voltage

CMOS 16-BIT BUS TRANSCEIVER fabricated

with sub-micron silicon gate and five-layer metal

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 nOE canbeused

to disable the device so that the buses are

effectively isolated. The A-port interfaces with the

3V bus, the B-port with the 2.5V and 1.8V bus.

All inputs are equipped with protection circuits

against static discharge, giving them 2KV ESD im-

munity and transient excess voltage. All floating

bus terminals during High Z State must be held

HIGH or LOW.
