Abstract
A MOS type output driver circuit including an output circuit having first and second MOS type output transistors connected between a voltage supply and ground. The gates of the first and second output transistors are respectively, supplied with first and second drive signals that are mutually inverted. The MOS type output driver circuit further includes a protective circuit for preventing the output transistors from being damaged by overcurrent when the output is shorted to ground.
