Abstract
A pair of dummy signal lines transmitting dummy signals, complementary to and synchronized with a normal signal, are arranged to form a set together with a normal transfer line transmitting the normal signal. In a device on a receiving side, one of the dummy signal lines is selected and coupled in accordance with the logic level of the normal signal, whereby two ringings occur in the opposite phases on the receiving side, and cancel each other so that ringing of the normal signal can be suppressed. An input/output interface, which can transfer a signal having a short level transition time without causing ringing, can be provided.
