IN74HC158A
QUAD 2-INPUT DATA SELECTORS/MULTIPLEXERS
High-Performance Silicon-Gate CMOS
The IN74HC158A 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
