A level conversion circuit has an input buffer circuit which includes bipolar transistors and a complementary type inverter circuit which includes a P-channel first field effect transistor and an N-channel second field effect transistor. An input signal having a small amplitude is inputted to directly a gate terminal of the first field effect transistor and to a gate of the second field effect transistor through a coupling capacitor with no time delay. The complementary type inverter circuit outputs an output signal having a large amplitude. The coupling capacitor is interposed between the gates of the first and second field effect transistors forming the inverter circuit and this arrangement enables the level conversion circuit to operate at a high speed and at a reduced power consumption.
