The KK74AC175 is identical in pinout to the LS/ALS175, HC/HCT175. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. This device consists of four D flip-flops with common Reset and Clock inputs, and separate D inputs. Reset (active-low) is asynchronous and occurs when a low level is applied to the Reset input. Information at a D input is transferred to the corresponding Q output on the next positivegoing edge of the Clock input. 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
