ABSTRACT:
A drive circuit includes a first level shift circuit outputting a potential higher than an input potential by a prescribed voltage; a pull-up circuit outputting to an output node a potential lower than an output potential of the first level shift circuit by the prescribed voltage; a second level shift circuit outputting a potential lower than the input potential by the prescribed voltage; a pull-down circuit outputting to the output node a potential higher than an output potential of the second level shift circuit by the prescribed voltage; and a capacitor connected between output nodes of the first and second level shift circuits. Accordingly, through-current is reduced.
