Abstract
An electronic control unit coupled to a transmission line of a differential signal includes: a first suppression circuit suppressing a ringing effect and decreasing an impedance of the line for a first time interval when a level of the differential signal changes; a second suppression circuits suppressing a ringing effect and decreasing the impedance of the line for a second time interval when the level of the differential signal changes; and a switching unit isolating the second suppression circuit from the line when the operation power source energizes the electronic control unit, and connecting the second suppression circuit to the line when the operation power source does not energize the electronic control unit.
