Zusammenfassung:A semiconductor device includes first to sixth transistors of enhancement type. The first and fourth transistors are of p-channel type. The second, third, fifth and sixth transistors are of n-channel type. A breakdown voltage of the third transistor is lower than a breakdown voltage of the second transistor. A breakdown voltage of the sixth transistor is lower than a breakdown voltage of the fifth transistor. The first to third transistors are connected in series between a first power supply potential and a second power supply potential lower than the first power supply potential. The fourth to sixth transistors are connected in series between the first power supply potential and the second power supply potential.
