TECHNICAL DATA
IN74AC174
Hex D Flip-Flop with Common Clock and Reset
High-Speed Silicon-Gate
CMOS
The IN74AC174 is identical in pinout to the LS/ALS174, HC/HCT174. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. This device consists of six D flip-flops with common Clock and Reset inputs. Each flip-flop is loaded with a low-to-high transition of the Clock input. Reset is asynchronous and active-low. Outputs Directly Interface to
CMOS, NMOS, and TTL Operating
Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 µA; 0.1 µA @ 25°C High Noise Immunity Characteristic of
CMOS Devices Outputs Source/Sink 24mA
ORDERING INFORMATION IN74AC174N Plastic IN74AC174D SOIC TA = -40° to 85° C for all packages
