54AC174 • 54ACT174
Hex D Flip-Flop with Master Reset
General Description
The ’AC/’ACT174 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 dur-
ing the LOW-to-HIGH clock transition. The device has a
Master Reset to simultaneously clear all flip-flops.
n Outputs source/sink 24 mA

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 recom-
mend operation of FACT™ circuits outside databook specifications.
