MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selector/Multiplexer High Performance Silicon Gate CMOS The MC54/74HC158 is identical in pinout to the LS158.
The device inputs are compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
These devices route 2 nibbles (A or B) to a single port (Y) as determined by the Select input.
The data is presented at the outputs in inverted form for the HC158.
