DM74ALS5245 Octal 3-STATE Transceiver

October 1986

Revised February 2000

DM74ALS5245

Octal 3-STATE Transceiver

General Description

This octal bus transceiver is designed for asynchronous

two-way communication between data buses. The inputs

include hysteresis which provides improved noise rejec-

tion. Data is transmitted either from the A bus to the B bus

or from the B bus to the A bus depending on the logic level

of the direction control (DIR) input. The device can be dis-

abled via the enable input (G) which causes the outputs to

enter the high impedance mode so the buses are effec-

tively isolated.

Features

Input Hysteresis

Low output noise generation

High input noise immunity

Advanced oxide-isolated, ion implanted Schottky TTL

process

Switching specification guaranteed over the full temper-

ature and V

range

PNP inputs to reduce input loading
