Introductions to Flip-Flops


Flip-flops and latches are fundamental building blocks of digital electronics. A flip-flop is a circuit that has two stable states and can be used to store state information. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic.

A latch is asynchronous and level triggered, meaning the outputs can change as soon as the input changes (or at least after a small propagation delay). Whereas a Flip Flop is synchronous and edge triggered, i.e. the output changes when a control signal goes from high to low or low to high.

Upon completion of the presentation you will be able to:

  • Apply knowledge of mathematics, scince and engineering fundamentals to well defined electrical and electronic engineering procedures and practices.
  • Simplify and design combinational and sequential logic circuits by using the Boolean Algebra and the Karnaugh Maps.
  • Draw Logic Diagrams, truth tables and timing diagrams for all common flip flops and use these to implement sequential logic circuits correctly.
  • Understand Types of Flip-Flop, Truth Tables, Symbols, Timing Diagram and its application in Logic Circuits.
  • Construct Types of Flip Flop using Types of Logic Gates by Drawing Symbols and Truth Tables, and Timing Diagram.
