D Type Flip Flop

Flip flop chips are a subtype of integrated chips, or ICs, and primarily used in flip flop circuits. Flip flop circuits are nonlinear circuits that can ‘flip’ back and forth between two stable states, although importantly they differ from latches in that they have a control signal (clock) input.

What’s special about a D-type flip flop in particular?

  • D-type flip flops are also clocked flip flops, and are among the most important types ICs in many circuits
  • A clocked D-type flip-flop has two stable states, and operates with a delay in input by one clock cycle, which is why you’ll sometimes hear them referred to as as delay flip flop
  • Using numerous D-type flip-flops in an array or cascade can therefore enable electronics engineers to create delay circuits, used in a great many everyday devices and applications like digital TVs
  • Flip flop ICs typically feed back output from one of their gates to be processed with an incoming input signal - new input signals are mixed with the IC’s previous output signal, such that the flip flop’s own outputs are dependent upon its previous state
    • A D-type flip flop IC is used to track and store these input, storing values that fall on the ‘d’ or data line
    • In this sense, a D-type flip flop is effectively functioning as a basic memory cell within the flip flop circuit

We sell an extensive range of electrical prototyping and circuit building tools, components and accessories, including a wide selection of D-type flip flops from leading brands such as Texas Instruments, ON Semiconductor, Toshiba and Nexperia.
