MC74HC157A Datasheet | onsemi

Quad 2-Input Data Selectors/Multiplexers High- Performance Silicon- Gate CMOS The MC74HC157A is identical in pinout to the LS157. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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. Features - 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 mA - High Noise Immunity...
