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.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0
