A semiconductor device includes a chip, a plurality of pads that is formed along the perimeter of the chip, and that includes a first pad and a second pad placed next to the first pad, and a circuit that is formed on the chip, and that is coupled to the first and second pads. The circuit includes first and second conductivity type transistors that are coupled between first and second reference potentials and a comparator that includes a first input node coupled to the first pad and a second input node coupled to the second pad, and that compares a potential of the first input node with a potential of the second input node. The first pad is coupled to gate electrodes of the first and second conductivity type transistors, and the second pad is coupled to drain electrodes of the first and second conductivity type transistors.
