MC74HC253 - Dual 4-Input Data Selector/Multiplexer
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Dual 4-Input Data Selector/ Multiplexer with 3-State Outputs High Performance Silicon Gate CMOS The MC74HC253 is identical in pinout to the LS253.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The Address inputs select one of four Data inputs from each multiplexer.
Each multiplexer has an active low Output Enable control and a three state noninvert
