Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply,temperature, and output/input loading variables. National does not recommend operation of FACT™ circuits outside databook specifications.

The 54ACT174 is a high-speed hex D 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 54ACT174 has a Master Reset to simultaneously clear all flip-flops.
