ABSTRACT:
An output buffer circuit includes first and second transistors of a first conductivity type, having first terminals connected in common and second terminals connected to first and second power supplies. The output buffer circuit also includes third and fourth transistors of a second conductivity type, having first terminals connected in common and second terminals connected to third and fourth power supplies. First and second resistors connected in series are connected between a common connecting point of the first and second transistors, and a common connecting point of the third and fourth transistors. A connecting neutral point serves as an output terminal. Damage resulting from excessive current or pass-through current when executing a switching process can thereby be prevented.
