IN74ACT109
DUAL J-K FLIP-FLOP
WITH SET AND RESET
High-Speed Silicon-Gate CMOS
The IN74ACT109 is identical in pinout to the LS/ALS109,
HC/HCT109. The IN74ACT109 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This device consists of two J-K flip-flops with individual set,
reset, and clock inputs. Changes at the inputs are reflected at the
outputs with the next low-to-high transition of the clock. Both Q to
Q outputs are available from each flip-flop.
• 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 high as long as}
Set and Reset are low, but the output
states are unpredictable if Set and Reset
go high simultaneously.
