PIN AND FUNCTION COMPATIBLE WITH

LATCH-UP PERFORMANCE EXCEEDS

500mA (JESD 17)

ESD PERFORMANCE:

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

HBM > 2000V (MIL STD 883 method 3015);

MM > 200V

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.

DESCRIPTION

The 74LCX245 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 high speed 3.3V applications; it can be

interfaced to 5V signal environment for both inputs

and outputs.

All floating bus terminals during High Z state must

be held HIGH or LOW.
