Abstract
An electronic device uses, as power, a first voltage and a second voltage lower than the first voltage. The electronic device includes: an internal circuit configured to be driven by the second voltage, and output an output signal having a level corresponding to the second voltage; and an interface circuit configured to receive the output signal, the first voltage, and the second voltage, shift the output signal to a level corresponding to the first voltage, and provide the shifted output signal to a pad. The interface circuit includes an ESD (electrostatic discharge) block connected to the pad. The interface circuit further includes a plurality of transistors, and all of the transistors of the interface circuit are driven at the second voltage and broken at the first voltage.
