Dual 4-Input Multiplexer, Three-State
August 1998 - Revised May 2000
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 VCC = 5V, TA = 25oC, CL = 50pF
• Exceeds 2kV ESD Protection MIL-STD-883, Method
3015

NOTES:
6. Test one output at a time for a 1-second maximum duration. Measurement is made by forcing current and measuring voltage to minimize
power dissipation.
7. Test verifies a minimum 50Ω transmission-line-drive capability at 85oC, 75Ω at 125oC.
