Abstract
A D-type flip-flop arrangement includes first and second latches .Circuitry interposed between the latches blocks any metastable condition that may occur in the first latch from propagating into the second latch. Additionally, the arrangement minimizes the likelihood that the first latch will enter a metastable condition and, if it does, resolves the condition extremely rapidly.
