Abstract
An integrated circuit includes a data processing circuit, an electrostatic discharge (ESD) protection circuit which is connected between a voltage rail and a ground rail and protects the data processing circuit from an ESD event on the voltage rail, and a switch circuit for controlling a connection between the voltage rail and the data processing circuit in response to a control signal.
Claims19
An integrated circuit, comprising:
- a data processing circuit;
- an electrostatic discharge (ESD) protection circuit which is connected between a voltage rail and a ground rail, and protects the data processing circuit from an ESD event on the voltage rail;
- and
- a switch circuit for controlling a connection between the voltage rail and the data processing circuit in response to a control signal,
- wherein the switch circuit includes:
- a first switch which is connected between the voltage rail and the data processing circuit and includes a first control terminal;
- and
- a second switch which is connected between the first control terminal and the ground rail, includes a second control terminal and controls a connection between the first control terminal and the ground rail in response to the control signal input to the second control terminal.
