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.

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 C MOS tecnology.

This IC is intended for two-way asynchronous

communication between data buses and the

direction of data transmission is determined by

PIN CONNECTION AND IEC LOGIC SYMBOLS
