Abstract
A semiconductor device includes: a semiconductor chip including a level shift circuit to output a high amplitude signal from an input of a logical signal, the level shift circuit including a series coupling circuit coupled to a second power supply, a control circuit coupled to the series coupling circuit for controlling the series coupling circuit based on the logical signal, and a first potential conversion circuit coupled between the series coupling circuit and the control circuit and coupled to a first power supply. The series coupling circuit includes a plurality of first MOS transistors coupled in series between the second power supply and a reference power supply, and a plurality of second MOS transistors coupled in series between the second power supply and the reference power supply in series with the plurality of first MOS transistors.
