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