KK74HC253A - Dual 4-Input Data Selector/Multiplexer
TECHNICAL DATA KK74HC253A Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Performance Silicon-Gate CMOS The KK74HC253A is identical in pinout to the LS/ALS253.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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.
Outputs Directl
