DESCRIPTION

The 74AC245 is an advanced high-speed CMOS

OCTAL

BUS

TRANSCEIVER

(3-STATE)

fabricated

with

sub-micron silicon gate and

double-layer metal wiring C2MOS tecnology.

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 floating bus terminals during HIGH-Z state

must be held HIGH or LOW

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
