Dual 4-Input Multiplexer, Three-State

Description

The CD74AC253 and ’ACT253 dual 4-input multiplexers that
utilize Advanced CMOS Logic technology. One of the four
sources for each section is selected by the common Select
inputs, S0 and S1. When theOutputEnable (
HIGH, the output is in the high-impedance state.
