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 dete.
