ABSTRACT:
A output circuit of a semiconductor integrated circuit comprises a prebuffer circuit, an output buffer circuit comprising first and second output buffer circuits for receiving the output of said prebuffer circuit, said first output buffer circuit comprising a CMOS inverter having its input terminal connected to the output terminal of said output buffer circuit and its output terminal connected to an output terminal, said second output buffer circuit comprising MOS transistors for electrically charging or discharging said output terminal and capacitances, the output of said prebuffer circuit being supplied to the gates of the MOS transistors through the respective capacitances. Such an output circuit can effectively reduce simultaneous switching noise without deteriorating its load driving capability.
