Patent ID: 7244993

Claim:
A driving circuit including a plurality of output terminals, comprising: a semiconductor substrate having a first conduction type; a first well having the first conduction type formed in the semiconductor substrate; a first diffusion layer having a second conduction type formed in the first well, the first diffusion layer related to a first output terminal of the plurality of output terminals; a second diffusion layer having the second conduction type formed in the first well, the second diffusion layer related to a second output terminal of the plurality of output terminals; and a third diffusion layer formed in the first well between the first diffusion layer and the second diffusion layer, the third diffusion layer including a fourth diffusion layer having the first conduction type, a fifth diffusion layer having the first conduction type, and a sixth diffusion layer having the second conduction type formed between the fourth diffusion layer and the fifth diffusion layer, wherein a voltage applied to the sixth diffusion layer is greater than a voltage applied to the first well.
