Fairchild Semiconductor 74AC174/74ACT174 Hex D-Type Flip-Flop with Master Reset Datasheet
This document provides a technical overview of the Fairchild Semiconductor 74AC174 and 74ACT174, which are high-speed hex D-type flip-flops designed primarily as 6-bit edge-triggered storage registers. The devices feature a common Master Reset input to simultaneously clear all flip-flops and transfer data on the LOW-to-HIGH clock transition.
