Abstract:
In a communications system for differential signals, a driver circuit is connected to a receiver circuit by a pair of differential signal lines. When data is not being transmitted, the differential signal lines are maintained at a predetermined electric potential, and when data is to be transferred, a differential signal is output at predetermined electric potentials. The receiver circuit switches between a power-down state and a normal state when detecting states of the electric potentials of the differential signal lines.
