Abstract
An over drive circuit and an input/output circuit are provided. The over drive circuit includes multiple P-type transistors connected to each other in series and a first N-type transistor connected to the P-type transistors in series. One end of the over drive circuit is coupled to a first voltage. Transistors connected in parallel connected to the first N-type transistor in series. Multiple N-type transistors with smaller size than the first N-type transistor are turned on in sequence.
