Abstract
A driver circuitry includes first-fifth inverters which have lower withstand voltage, and first-sixth transistors which have higher withstand voltage. In the first transistor, a first voltage is applied to a first end, and a second end is connected to the high withstand voltage element. The second transistor is connected to the first transistor. The second inverter is connected to the first inverter and the first transistor. The third inverter is connected to the first inverter. The third transistor is connected to the second inverter. The fourth transistor is connected to the third transistor. The fifth transistor is connected to the third inverter. The sixth transistor is connected to the fifth transistor. The fourth inverter is connected to the sixth transistor and the second transistor. The fifth inverter is connected to the fourth transistor, the fourth inverter, and the fourth inverter.
