Abstract
Abstract A logic flip flop arrangement wherein each of the two outputs of the flip flop has an output gate associated therewith, wherein an input of each of the output gates is connected to an output of a driving gate, and wherein at least one of the output gates has an output thereof combined with an output of that one of the driving gates which is associated with the other output gate to provide a logic function.
