74HC175; 74HCT175

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

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.

Features and benefits

  • Input levels:
    • For 74HC175: CMOS level
