Integrated circuit

Abstract

An integrated circuit includes an input/output pad for signal exchange with an external circuit, an electrostatic discharge (ESD) protection unit coupled to the input/output pad and configured to form an ESD path between a first voltage line and a second voltage line, a first drive transistor coupled between the first voltage line and the input/output pad, a first driving control unit coupled to a gate of the first drive transistor and configured to control the first drive transistor, a first dummy drive transistor coupled between the first voltage line and the input/output pad, and a first auxiliary driving control unit configured to supply the first voltage to a gate of the first dummy drive transistor in a normal operation mode, and float the gate of the first dummy drive transistor in a non-operation mode in which no power is supplied.
