Abstract
In a signal electric potential conversion circuit, a capacitor has one end receiving an input signal CIN, and the other end connected to a termination node N. A conversion circuit receives a potential IN of the termination node N. A connection element is provided between a power supply VDDH and the termination node N, and an impedance of the connection element is reduced when the potential IN is lower than a first potential. Another connection element is provided between the termination node Nand a ground power supply, and an impedance of the connection element is reduced when the potential IN is higher than a second potential.
