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. • • • • • • 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.
