A first differential signal received at an input terminal is input to non-inversion terminals of a first comparator and a receiving end device. A second differential signal lower than the first differential signal is received at another input terminal and is input to inversion terminals of a second comparator and the receiving end device. A first reference voltage higher than the first differential signal is applied to an inversion terminal of the first comparator, and a second reference voltage lower than the second differential signal is applied to a non-inversion terminal of the second comparator. When one input terminal is open-circuited or short-circuited, a voltage higher than the first reference voltage or a voltage lower than the second reference voltage is applied to the non-inversion terminal of the first comparator or the inversion terminal of the second comparator.
An interface circuit, which is connected to a data transmission line through a termination resistor at both a first signal input terminal and a second signal input terminal and receives a pair of differential signals transmitted through the data transmission line as reception data, comprising:
