Quad D-type flip-flop with reset; positive-edge trigger

The 74HC175; 74HCT175 are quad positive edge-triggered D-type flip-flops with individual data inputs (Dn) and both Qn and Qn outputs. The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously. The D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition is stored in the flip-flop and appears at the Q output. A LOW on MR causes the flip-flops and outputs to be reset LOW.

The device is useful for applications where both the true and complement outputs are required and the clock and master reset are common to all storage elements.
