Abstract
A semiconductor device includes light-emitting elements, a selection circuit, a control circuit, light-receiving elements, and switch elements. The selection circuit is configured to accept one input signal and output a signal for selecting an element to emit light among the light-emitting elements. The control circuit is configured to control the light-emitting elements, based on the signal outputted from the selection circuit. The light-receiving elements are each configured to receive light of each of the light-emitting elements and generate a signal for driving a switch, based on a light-receiving state. The switch elements are each configured to be driven by application of voltage outputted from each of the light-emitting elements.
