74AC174 • 74ACT174

Hex D-Type Flip-Flop with Master Reset

General Description

The AC/ACT174 is a high-speed hex D-type flip-flop. The

device is used primarily as a 6-bit edge-triggered storage

register. The information on the D inputs is transferred to

storage during the LOW-to-HIGH clock transition. The

device has a Master Reset to simultaneously clear all flip-

flops.
