74F175
Quad D-Type Flip-Flop
General Description
The 74F175 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 inputs is stored during the LOW-to-HIGH clock transition.
Both true and complemented outputs of each flip-flop are
provided. A Master Reset input resets all flip-flops, inde-
pendent of the Clock or D inputs, LOW.

Functional Description
The 74F175 consists of four edge-triggered D-type flip-
flops with individual D inputs and Q and Q outputs. The
Clock and Master Reset are common. The four flip-flops
will store the state of their individual D inputs on the LOW-
to-HIGH clock (CP) transition, causing individual Q and Q
outputs to follow. A LOW input on the Master Reset (MR)
will force all Q outputs LOW and Q outputs HIGH indepen-
dent of Clock or Data inputs. The 74F175 is useful for gen-
eral logic applications where a common Master Reset and
Clock are acceptable.
