Provided is an input/output matching circuit, which maintains electrostatic resistance by means of ESD elements, and which, at the same time, has high-speed communication performance without being affected by noise. In the present invention, a plurality of ESD elements having different frequency characteristics, and elements thereof are connected to each other by means of coils, thereby constituting a matching circuit of the ESD elements and the coils. |
