Abstract:
1. A semiconductor device, comprising: an interface including a first MOSFET and converting a terminal switch signal of input serial data into parallel data, the first MOSFET provided on an SOI substrate and having a back gate in a floating state and; a power supply including a second MOSFET and generating an ON potential higher than a potential of a power supply to be supplied to the interface, the second MOSFET provided on an SOI substrate and having a back gate connected to a source; a driver including a third MOSFET and outputting a control signal for controlling the ON potential to be in a high level according to the parallel data, the third MOSFET provided on an SOI substrate and having a back gate connected to a source; and a switch section provided on the SOI substrate and switching connection between terminals by inputting the control signal.
