Abstract

PURPOSE:To prefectly prevent the swing of the electric potential of input signals to value not more than earth potential while positively protecting a gate insulating film of an input element, by forming this circuit so that adequate bias be added to a gate of a MOS.FET. CONSTITUTION:When the electric potential of input signals applied to an input terminal swings in the positive direction in value not less than the yield voltage of a MOS.FET 11, a MOS.FET 12 is conducted by yield between a source and drain of the MOS.FET 12, and the excessive rise of the gate potential of the MOS.FET 11 is prevented, thus protecting the MOS.FET 11. When input potential shakes to potential not more than earth potential due to power source noises, etc., the source and drain of the MOS.FET 12 are reversed, and the MOS.FET 12 is conducted, thus preventing the drop of the potential of an input signal passage to value not more than earth potential.
