1. General description

The 74HC175; 74HCT175 is a quad positive-edge triggered D-type flip-flop with individual data

inputs (Dn) and complementary outputs (Qn and 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 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.
