PIN AND FUNCTION COMPATIBLE WITH

74 SERIES C3245

IMPROVED LATCH-UP IMMUNITY

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

DIR input. The enable input G can be used to

disable the device so that the buses are effectively

isolated.

DESCRIPTION

The 74LVXC3245 is

a dual supply 8 bit

configurable low voltage CMOS OCTAL BUS

TRANSCEIVER fabricated with sub-micron silicon

The A-port interfaces with the 3V bus, the B-port

with the 5V bus.

gate and double-layer metal wiring C MOS

technology. Designed for use as an interface

between a 3.3V bus and a 3.3V to 5V bus in a

mixed 3.3V/5V supply systems, it achieves high

speed operation while maintaining the CMOS low

power dissipation.

All inputs are equipped with protection circuits

against static discharge, giving them 2KV ESD

immunity and transient excess voltage.
