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.
