The KK74AC109 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 available from each flip-flop. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A; 0.1 A @ 25C High Noise Immunity Characteristic of CMOS Devices Outputs Source/Sink 24 mA
