Dual 4-Input Multiplexer with TRI-STATE® Outputs

General Description

The ’AC/’ACT253 is a dual 4-input multiplexer with

TRI-STATE outputs. It can select two bits of data from four

sources using common select inputs. The outputs may be in-

dividually switched to a high impedance state with a HIGH

on the respective Output Enable (OE) inputs, allowing the

outputs to interface directly with bus oriented systems.

Features

n ICC and IOZ reduced by 50%

n Multifunction capability

n Noninverting TRI-STATE outputs

n Outputs source/sink 24 mA

n ’ACT253 has TTL-compatible inputs

n Standard Military Drawing (SMD)

— ’AC253: 5962-87693

— ’ACT253: 5962-87761
