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...
