Variations in a receiving circuit employing differential signaling are reduced. The receiving circuit converts a first signal and a second signal which are supplied through differential signaling into a third signal which is a single-ended signal and outputs the third signal. The receiving circuit includes an operational amplifier, a first element, a first transistor, and a first circuit. The first element is connected to the first circuit through a first node to which the first transistor is connected. The first signal and the second signal that is the inverse of the first signal are supplied to the operational amplifier. The operational amplifier supplies an output signal to the first element, and a first preset potential is supplied to the first node through the first transistor. A signal including variations of the operational amplifier is stored in the first element in accordance with the first preset potential. The first circuit that is supplied with the first preset potential determines an initial value of the third signal without being influenced by the signal including variations of the operational amplifier.
