Functional Description
The HD74AC175 consists of four edge-triggered D 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
independent of Clock or Data inputs. The HD74AC175 is useful for general logic applications where a
common Master Reset and Clock are acceptable.
