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.
A high level on the Output Enable input sets all four Y outputs to a low level.
The HC157A is similar in function to the HC257 which has 3–state outputs.
