Patent ID: 7804331

Claim:
A semiconductor device comprising: an output stage circuit including a first conductive type first transistor and a second conductive type second transistor, the first conductive type first transistor being connected between a first power supply terminal and an output terminal, the second conductive type second transistor being connected between a second power supply terminal and the output terminal and having a leak current larger than that of the first transistor; and an input stage circuit outputting a logic value setting the first transistor to a non-conductive state and setting the second transistor to a conductive state in accordance with a logic circuit disable signal input when the output stage circuit is in a disable state, wherein the input stage circuit comprises an output fixing circuit fixing an output of the input stage circuit, wherein the output fixing circuit comprises a third transistor of the first conductive type and a fourth transistor of the second conductive type, gates of the third and fourth transistors connected to each other, wherein the fourth transistor is connected between the second power supply and the input terminal of the output stage converter.
