74HC74; 74HCT74

Dual D-type flip-flop with set and reset; positive edge-trigger

Rev. 8 — 9 February 2023

Product data sheet

1. General description

The 74HC74 and 74HCT74 are dual positive edge triggered D-type flip-flop. They have individual

data (nD), clock (nCP), set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs.

Data at the nD-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 nQ output. Schmitt-trigger action in the clock

input, makes the circuit highly tolerant to slower clock rise and fall times. Inputs include clamp

diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of

V_CC

2. Features and benefits
