Patent ID: 8675811

Claim:
A semiconductor device which is constituted by a plurality of transistors having an identical conductivity type, comprising: a first transistor which has a first terminal to which an input signal is supplied and a second terminal from which an output signal is outputted; a second transistor which has a first terminal to which a control signal is supplied and a second terminal which is connected to a control terminal of the first transistor; a fourth transistor which has a first terminal connected to a point at which the control terminal of the first transistor and the second terminal of the second transistor are connected to each other, and a control terminal to which an ON voltage is supplied; and a third transistor which has a first terminal connected to a second terminal of the fourth transistor, and a control terminal to which an inversion signal of the control signal is supplied, a control terminal of the second transistor, the first terminal of the second transistor, and a second terminal of the third transistor being connected to one another.
