DESCRIPTION

The 74ACT245 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.

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

IT IS PROHIBITED TO APPLY A SIGNAL TO A

TERMINAL WHEN IT IS IN OUTPUT MODE AND

WHEN A BUS THERMINAL IS FLOATING (HIGH

IMPEDANCE STATE) IT IS REQUIRED TO FIX

THE INPUT LEVEL BY MEANS OF EXTERNAL

PULL DOWN OR PULL UP RESISTOR.
