... Dual 4-Input Data Selector/Multiplexer with 3-State Otputs High-Performance Silicon-Gate CMOS The IN74HC253A 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 ...
