Abstract
A semiconductor circuit has a first transistor, a second transistor, a third transistor, and a fourth transistor. The first and fourth transistors are a first conduction type, and the second and third transistors are a second conduction type opposite to the first conduction type. The semiconductor circuit employs a first power supply line for supplying a first voltage, a second power supply line for supplying a second voltage, and a third power supply line for supplying a third voltage outside of the range determined by the first voltage and the second voltage. The first, second, and third transistors are connected in series between the second power supply line and the third power supply line, and the fourth transistor is connected between an input terminal and a control electrode of the first transistor.
