TECHNICAL DATA IN74AC109 Dual J-K Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The IN74AC109 is identical in pinout to the LS/ALS109,HC/HCT109.
The device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LS/ALS 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 a
