Abstract
A semiconductor integrated circuit includes a power supply switch circuit which uses a PMOS transistor and an NMOS transistor to select a first power supply voltage applied to a first power supply input terminal or a second power supply voltage applied to a second power supply input terminal, and output the selected voltage as a power supply voltage to a third power supply output terminal, a first switch control circuit connected to the gate of the PMOS transistor, and a second switch control circuit connected to the gate of the NMOS transistor.
