Abstract : A logic circuit for the transfer of true and complement binary digital bits of information employs 'single rail' techniques to eliminate several elements required in prior art 'double rail' logic circuits. A J-K flip-flop is arranged to receive each true binary digital bit of data information at both its J and K inputs and upon being clocked produces the 'true' output relative to the data input when the J-K flip-flop has been previously put into its 'clear' condition, and produces complement outputs when the flip-flop has been previously put in the 'set' condition. Simplification of the logic circuit by elimination of a number of elements results in cost savings over comparable prior art circuits and improved speed of operation as well.
