Semiconductor integrated circuit

A semiconductor integrated circuit comprising:

• a substrate on which semiconductor circuit elements are formed;
• an output terminal formed on the substrate, the output terminal being connected to an external load;
• an internal signal line formed on the substrate, the internal signal line connecting the output terminal to an internal node;
• a voltage generator formed on the substrate, for generating a voltage and supplying the voltage to the internal node for output through the internal signal line and the output terminal to the external load;
• a voltage attenuating element formed on the substrate and connected to the internal signal line, for attenuating voltage swings on the internal signal line;
• and
• a voltage limiting circuit formed on the substrate and connected to the internal node, for limiting the voltage at the internal node to a predetermined range if, after attenuation of the voltage swings by the voltage limiting circuit, the voltage at the internal node exceeds the predetermined range.
