ULTIPLEXER
High-Speed Silicon-Gate CMOS
The IN74ACT158 is identical in pinout to the LS/ALS138,
HC/HCT138. The IN74ACT158 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
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.
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
