ABSTRACT:
A driver circuit comprises a bipolar transistor for passing current from a power supply potential V.sub.CC to an output terminal, two CMOS inverters connected between an input terminal and the output terminal, a diode for passing current from the output terminal to the input terminal, and an NMOSFET for passing current from the input terminal to a power supply potential V.sub.EE. When a signal applied to the input terminal falls from an "H" level to an "L" level, the potential of the output terminal is changed from V.sub.CC to V.sub.EE. At the time, current flows from the output terminal to the input terminal through the diode. In addition, the current flows to the power supply potential V.sub.EE through the NMOSFET. When the signal applied to the input terminal rises from the "L" level to the "H" level, the potential of the output terminal is changed from the V.sub.EE to the V.sub.CC. At that time, current flows from the power supply potential V.sub.CC to the output terminal through the bipolar transistor.
