Abstract

See full text

Provided is a switch circuit capable of reliably controlling the transmission or interruption of a voltage of from GND to VDD to an internal circuit even when a positive or negative voltage is input to an input terminal. By adding PMOS transistors to NMOS transistors constituting the switch circuit and controlling gates of the PMOS transistors by a voltage of the input terminal, the transmission or interruption of the voltage of from GND to VDD can be reliably controlled.
