KK74AC109 Overview
KK74AC109 Dual J-K Flip-Flop with Set and Reset High-Speed Silicon-Gate CMOS The KK74AC109 is identical in pinout to the LS/ALS109,HC/HCT109. The device inputs are patible with standard CMOS outputs, with pullup resistors, they are patible with LS/ALS outputs. This device consists of two J-K flip-flops with individual set, reset, and clock inputs.
