A small amplitude output circuit comprises an output section (11) for receiving a logic signal to output a small amplitude signal, a level sense circuit (13, 13A) for sensing the rise or fall of H-level or L-level voltage of an output voltage at an output terminal (OUT1), and a level control circuit (15, 15A) for responding to the output of the level sense circuit (13, 13A) to suppress the rise or fall of the H-level or L-level of the output voltage. The output circuit suppress voltage variations caused by variations in fabrication process of transistors, ambient temperature and source voltage noise. <IMAGE> |
