TECHNICAL DATA
KK74HC158A
Quad 2-Input Data Selectors/Multiplexers
High-Performance Silicon-Gate CMOS
The KK74HC158A 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
