摘要：
In a data transmission, a driving circuit 14 drives a light receiving element 15 in accordance with data from an external control circuit. In accordance with IrDA or remote control communication, driving capability of the driving circuit is changed. In a data reception, received data is transferred to a first or a second signal processing circuit in accordance with the IrDA or remote control communication and processed according to each communication format. In this configuration, a single light emitting or light receiving element permits data communication in different kinds of data communication formats.
