Disclosed is a receiving device that includes a differential input circuit having an inverting input terminal and a non-inverting input terminal to which the differential signal is input; an abnormality detection circuit that detects an abnormality in a wiring connected to the inverting input terminal and the non-inverting input terminal; and a control circuit that sets an output signal of the receiving device in a predetermined status when the abnormality is detected. The abnormality detection circuit detects the abnormality if a status, in which a potential difference between a voltage of the inverting input terminal and a voltage of the non-inverting input terminal is less than a minimum potential difference in a predetermined range of the potential difference between the voltage of the inverting input terminal and the voltage of the non-inverting input terminal, continues for a predetermined time or more.
