Dual J-K Flip-Flop
with set and Reset
High-Performance Silicon-Gate CMOS

The KK74HCT109A is identical in pinout to the LS/ALS109. The KK74HCT109A 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
