IN74ACT112 Datasheet, PDF (1/6 Pages) Integral Corp. – DUAL J-K FLIP-FLOP WITH SET AND RESET

TECHNICAL DATA
Dual J-K Flip-Flop
with Set and Reset
High-Speed Silicon-Gate CMOS
IN74ACT112
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

* Both outputs will remain low as long as Set and Reset are
low, but the output states are unpredictable if Set and Reset
go high simultaneously
