PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 245

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.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

The 74LVQ245 is a low voltage CMOS OCTAL

BUS TRANSCEIVER (3-STATE fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS technology. It is ideal for low power

and low noise 3.3V applications.

All floating bus terminals during High Impedance

State must be held HIGH or LOW.
