The 74HCT174D is a hex positive edge-triggered D-type Flip-flop with individual data inputs Dn and outputs Qn. 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. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
