Abstract
A multiplexer receives multiple differential signals, selects one differential signal, and outputs, via an output port, the differential signal thus selected. The multiple differential signals are respectively input to multiple differential input ports. Multiple buffers are respectively provided to the multiple differential input ports. Each buffer includes a differential input terminal connected to a corresponding differential input port, and a differential output terminal connected to an output port. Each buffer is configured to be capable of switching states, according to the control signal, between an enable state in which a differential signal that corresponds to a differential signal input to the differential input terminal is output, and a disable state in which current consumed by the buffer becomes substantially zero, and the differential output terminal thereof is set to a high-impedance state.
