Abstract
An electronic circuit includes a first level shift circuit, a second level shift circuit, an internal circuit, a high voltage circuit, first and second transistors, and first and second protective circuits. The first and second protective circuits perform control the first and second transistors so as to make them non-conductive when at least one of a plurality of types of power supply voltages becomes equal to or less than a predetermined value.
