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.

• Typical Propagation Delay

- 6.3ns at V

= 5V, T = 25 C, C = 50pF
