74HCT175D,652

The 74HCT175D is a quad positive-edge triggered D-type Flip-flop with individual data inputs (Dn) and complementary outputs (Qn and Qn\). The common clock 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 will be stored in the flip-flop and appear at the Q output. A low on MR\ causes the flip-flops and outputs to be reset low. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
