The IN74AC253 is identical in pinout to the LS/ALS253, HC/HCT253. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The Address Inputs of the IN74AC253 select one of four Data Inputs from each multiplexer. Each multiplexer has an active-low Output Enable control and a three-state noninverting output.
