KK74HC109A, Dual J-K Flip-Flop

TECHNICAL DATA KK74HC109A Dual J-K Flip-Flop with Set and Reset High-Performance Silicon-Gate CMOS The KK74HC109A is identical in pinout to the LS/ALS109.

The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LS/ALSTTL outputs.

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
