KODENSHI KK74HC174AD

TECHNICAL DATA
KK74HC174A
Hex D Flip-Flop with
Common Clock and Reset
High-Performance Silicon-Gate CMOS
The KK74HC174A is identical in pinout to the LS/ALS174. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LS/ALSTTL 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
• High Noise Immunity Characteristic of CMOS Devices

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
