FAST? is a Trademark of Fairchild Semiconductor.
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.
