CD74HC253 - High Speed CMOS Logic Dual 4-Input Multiplexers

The CD74HC253 and CD74HCT253 are dual 4-to-1 line selector/multiplexers having three-state outputs. One of four sources for each section is selected by the common select inputs, S0 and S1. When the output enable (1OE\, 2OE\) is HIGH, the output is in the high-impedance state.
