The D flip-flop is widely used, and known as a "data" flip-flop. The D flip-flop captures the value of the D-input at a definite portion of the clock cycle (such as the rising edge of the clock). That captured value becomes the Q output. At other times, the output Q does not change. [23] [24] The D flip-flop can be viewed as a memory cell, a ...

Date/Time Thumbnail Dimensions User Comment; current: 20:33, 25 September 2006: 800 × 250 (32 KB): Plugwash~commonswiki: change to nand as per comment on wikipedia page using image. i suspect whoever draw this forgot about the inverted inputs of a nand rs flip flops.
Flip-flop excitation tables [ edit ] In order to complete the excitation table of a flip-flop , one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.

Random flip-flop (RFF) is a theoretical concept of a non-sequential logic circuit capable of generating true randomness. By definition, it operates as an "ordinary" edge-triggered clocked flip-flop , except that its clock input acts randomly and with probability p = 1/2. [ 1 ]
