Dual 4-Input Multiplexer, Three-State
Features
Description
• Buffered Inputs
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 the Output Enable (1OE or 2OE) is
HIGH, the output is in the high-impedance state.
