KK74HC109A Overview
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 patible with standard CMOS outputs, with pullup resistors, they are patible with LS/ALSTTL outputs. This device consists of two J-K flip-flops with individual set, reset, and clock inputs.
