Introduce the D flip-flop and provide an excitation table and a sample timing analysis.. A. Yaicharoen. 2. Flip-Flops. A . flip-flop is a bi-stable device: a circuit having 2 stable conditions (0 or 1. ). A flip-flop circuit has two outputs and the outputs of the flip-flop always complement each other, . and . Flip-Flops. Jack . Ou. , Ph.D. .. Sequential Circuits. New output are dependent on the inputs and the preceding values of outputs..
