Last time, we saw how latches can be used as memory in a circuit.. Latches introduce new problems:. We need to know when to enable a latch.. We also need to quickly disable a latch..

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.. Characteristic: output nodes are intentionally connected back to inputs.. Register is built with gates, but has memory.. The only type of flip-flop required in this class – the D flip-flop . Has at least two inputs (both 1-bit): D and . clk. Has at least one output (1-bit): Q. COE . 202. Digital Logic Design. Dr. .
