IN74ACT112

1

WITH

High-Speed Silicon-Gate CMOS

The IN74ACT112 is identical in pinout to the LS/ALS112,

HC/HCT112. The IN74ACT112 may be used as a level converter

for interfacing TTL or NMOS outputs to High Speed CMOS

inputs.

Each flip-flop is negative-edge clocked and has active-low

asynchronous Set and Reset inputs.

• 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
