Dual 4-Input Data Selector/Multiplexer
High−Performance Silicon−Gate CMOS
MC74HC153A
The MC74HC153 is identical in pinout to the LS153. 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 Strobe control and a noninverting output.
The HC153 is similar in function to the HC253, which has 3−state outputs.
