Quad D Flip-Flop
General Description
The ’AC/’ACT175 is a high-speed quad D flip-flop. The de-
vice is useful for general flip-flop requirements where clock
and clear inputs are common. The information on the D in-
puts is stored during the LOW-to-HIGH clock transition. Both
true and complemented outputs of each flip-flop are pro-
vided. A Master Reset input resets all flip-flops, independent
of the Clock or D inputs, when LOW.

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.
