Dual 4-Input Multiplexer with 3-STATE Outputs

General Description

Features

The AC/ACT253 is a dual 4-input multiplexer with 3-STATE

outputs. It can select two bits of data from four sources

using common select inputs. The outputs may be individu-

ally 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.

■ I_CCand I_OZreduced by 50%

■ Multifunction capability

■ Non inverting 3-STATE outputs

■ Outputs source/sink 24 mA

■ ACT253 has TTL-compatible inputs
