Patent ID: 8289072

Claim:
A semiconductor switch comprising: a voltage generator configured to generate a first potential and a negative second potential, the first potential being higher than a power supply voltage supplied to a power supply terminal; a driver connected to an output of the voltage generator and including a first level shifter and a second level shifter, the first level shifter being configured to output the first potential in response to input of high level and to output low level in response to input of low level, and the second level shifter being configured to output the first potential in response to input of the first potential of an output of the first level shifter and to output the second potential in response to input of low level of the output of the first level shifter; a switch section configured to switch connection between terminals in response to an output of the driver; and a power supply controller configured to control the output of the voltage generator to be connected to the power supply terminal during a first period after supplying the power supply voltage to the power supply terminal and control the output of the voltage generator to be disconnected from the power supply terminal after expiration of the first period.
