High–Performance Silicon–Gate CMOS
The MC74HC158A 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 HC158A. A high level on the Output Enable input sets all four
Y outputs to a high level for the HC158A.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2 to 6V
Low Input Current: 1
