74HC157A - Quad 2-Input Data Selectors/Multiplexers
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Quad 2-Input Data Selectors/Multiplexers High Performance Silicon Gate CMOS The MC54/74HC157A is identical in pinout to the LS157.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input.
The data is presented at the outputs in noninverted form.
