TECHNICAL DATA

8-Input Data Selector/Multiplexer

High-Speed Silicon-Gate CMOS

IN74ACT151

The IN74ACT151 is identical in pinout to the LS/ALS151,

HC/HCT151. The IN74ACT151 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The device selects one of the eight binary Data Inputs, as determined

by the Address Inputs. The Strobe pin must be at a low level for the

selected data to appear at the outputs. If Strobe is high, the Y output is

forced to a low level and the Y output is forced to a high level.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

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

• Outputs Source/Sink 24 mA
