TECHNICAL DATA
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.
•

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 hi gh
simultaneously.
