Abstract
An apparatus for a transparent master/slave flip-flop logic circuit including a single line connected to the transparency input of the logic macro so that when the line is active input data will pass through the flip-flop, unless the scan signal is also active, in which case the flip-flop will return to a clocked (latching) status.
