Quad 2-Input Data Selectors/Multiplexers High-Performance Silicon-Gate CMOS

The SL74HC158 is identical in pinout to the LS/ALS158. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL 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 invertered form. A high level on the Output Enable input sets all four Y outputs to a high level.

? Outputs Directly Interface to CMOS, NMOS, and TTL

? Operating Voltage Range: 2.0 to 6.0 V

? Low Input Current: 1.0 μA

? High Noise Immunity Characteristic of CMOS Devices
