Abstract
A switch 17 for short-circuiting is connected between the outputs of circuits 15 and 16 each of which outputs a pair of complementary signals .0.S1 and .0.R1. The circuits 15 and 16, and the switch 17 are controlled by a changeover control circuit 18 in response to an input signal .0.A1. To effectively utilizes electric charge which has become unnecessary on a complementary signal line pair, the circuit 18 comprises an edge detecting circuit for providing a pulse to the switch 17 to make it on in response to the edge of the signal .0.A1, and a state control circuit for making the outputs of the circuits 15 and 16 in a high impedance state while the switch 17 being on, and for making the logic states of the signals .0.S1 and .0.R1 completely transit in response to disappearance of the pulse while the switch 17 being off.
