<p>An interface circuit (100) includes a first (INN) and a second (INP) input terminal, a first output transistor (Q121), a second output transistor (Q122), a first output controller (107) for implementing control according to a voltage supplied to the first and the second input terminal so that a predetermined current appears at a control terminal of the first output transistor if the first output transistor is in saturated state and supplies a predetermined current to the control terminal of the first output transistor if the first output transistor is in shutoff state, and a second output controller (108) for implementing control according to a voltage supplied to the first and the second input terminal so that a predetermined current appears at a control terminal of the second output transistor if the second output transistor is in saturated state and supplies a predetermined current to the control terminal of the second output transistor if the second output transistor is in shutoff state.
