74ALVC74

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

Rev. 6 — 27 July 2021

Product data sheet

1. General description

The 74ALVC74 is a dual positive edge triggered, D-type flip-flop. It has individual data (nD) inputs,

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

The set and reset are asynchronous active LOW inputs that operate independently of the clock

input. Information on the data input is transferred to the nQ output on the LOW-to-HIGH transition

of the clock pulse. The nD inputs must be stable one set-up time prior to the LOW-to-HIGH clock

transition, for predictable operation. Schmitt-trigger action in the clock input makes the circuit highly

tolerant to slower clock rise and fall times.
