ABSTRACT:
A signal from an input terminal is supplied to a CMOS inverter. An output from the inverter is supplied to the bases of a pnp bipolar transistor and an npn bipolar transistor. The base of an output pnp bipolar transistor is connected to the emitter of one bipolar transistor through a resistor for setting a base current. The base of an output npn bipolar transistor is connected to the emitter of the other bipolar transistor through a resistor for setting a base current. The emitter of one output bipolar transistor is connected to a node for receiving a high-potential power supply voltage, and its collector is connected to an output terminal. The emitter of the other output bipolar transistor is connected to a node for receiving a low potential power supply voltage and its collector is connected to the output terminal.
