Description

The IN74HC253A is identical in pinout to the LS/ALS253. The device inputs are compatible with standard CMOS utputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

The Address Inputs select one of four Data Inputs of the IN74HC253A from each multiplexer. Each multiplexer has an active-low Output  nable control and a three-state noninverting output.
