Abstract
A switching circuit includes a first input terminal, an output terminal, and a first circuit that switches between outputting and not outputting, to the output terminal, a first voltage that is inputted to the first input terminal. The first circuit includes a first transistor and a second transistor that are connected in series between the first input terminal and the output terminal and a first voltage-dividing circuit that divides the first voltage and supplies the first voltage thus divided to a common node between the first transistor and the second transistor.
