Abstract
An output circuit includes an output block and a predrive block for driving the output block based on an input signal. The predrive block has a clamp unit connected between the gate terminal of a first output transistor and the gate terminal of a second output transistor to limit the potential of the gate terminal of the first output transistor to a value of not more than a first potential and limit the potential of the gate terminal of the second output transistor to a value of not less than a second potential.
