A logic circuit for outputting signals corresponding to an input signal depending on a clock signal sent from an external source includes at least one synchronous flip-flop being synchronized with the clock signal, so that the flip-flop latches the input signal, and a unit for controlling an input of the clock signal to the flip-flop based on a difference between logic levels of an output signal of the flip-flop and an input signal newly latched by the flip-flop.
