DESCRIPTION

The 74LCX245 is a low voltage CMOS OCTAL

BUS TRANSCEIVER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. It is ideal for low power

and high speed 3.3V applications; it can be

interfaced to 5V signal environment for both inputs

and outputs.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

This IC is intended for two way asynchronous

communication between data buses; 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.

All floating bus terminals during High Z state must

be held HIGH or LOW.
