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 noninverting output.
The HC253 is similar in function to the HC153 which does not have three–state outputs.
