The KK74AC112 is identical in pinout to the LS/ALS112, HC/HCT112. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. Each flip-flop is negative-edge clocked and has active-low asynchronous Set and Reset inputs. 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
