SL74HC174D

Hex D Flip-Flop with Common Clock and Reset High-Performance Silicon-Gate CMOS

System Logic Semiconductor 

SL74HC174

Hex D Flip-Flop with

Common Clock and Reset

High-Performance Silicon-Gate CMOS

The SL74HC174 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
