74LV74: Dual D-type flip-flop with set and reset; positive-edge trigger
The 74LV74 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.
