TECHNICAL DATA

IN74ACT157

Quad 2-Input Data Selector/Multiplexer

High-Speed Silicon-Gate CMOS

The IN74ACT157 is identical in pinout to the LS/ALS157,

HC/HCT157. The IN74ACT157 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

noninvertered form. A high level on the Output Enable input sets all four

Y outputs to a low level.

TTL/NMOS Compatible Input Levels

Outputs Directly Interface to CMOS, NMOS, and TTL

Operating Voltage Range: 4.5 to 5.5 V

Low Input Current: 1.0 μA; 0.1 μA @ 25°C

Outputs Source/Sink 24 mA
