Abstract
An output device is disclosed for restraining a ringing caused when the operation of a semiconductor integrated circuit device is speeded up. This output device includes first, second and third N channel transistors. The first N channel transistor has its gate electrode connected to receive an input signal, its drain electrode connected to an output terminal, and its source electrode connected to the drain electrodes of the second and third N channel transistors. The second N channel transistor has its gate electrode and drain electrode connected to each other and its source electrode grounded. The third N channel transistor has an on resistance value matching with the characteristic impedance of a load connected to the output terminal and has its source electrode grounded. When the level of the output signal is equal to or less than the threshold voltage of the second N channel transistor, the second N channel transistor is turned off, and the amount of an output current is limited by the on resistance of the third N channel transistor.
