IN74ACT151
8-INPUT DATA SELECTOR/MULTIPLEXER
High-Speed Silicon-Gate CMOS
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
