SEMICONDUCTOR TECHNICAL DATA
Quad 2-Input Data
Selector/Multiplexer
High–Performance Silicon–Gate CMOS
The MC54/74HC158 is identical in pinout to the LS158. The device
inputs are compatible with Standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
These devices route 2 nibbles (A or B) to a single port (Y) as deter-
mined by the Select input. The data is presented at the outputs in inverted
form for the HC158. A high level on the Output Enable input sets all four Y
outputs to a high level for the HC158.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2 to 6V
• Low Input Current: 1µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance With the JEDEC Standard No. 7A Requirements
• Chip Complexity: 74 FETs or 18.5 Equivalent Gates
