Integrated circuit with device for protecting against electrostatic discharges

摘要

Integrated circuit (20) comprising:
- a substrate of semiconductive material;
- a first circuit environment (CE_1) made from said substrate, comprising a first pair of power supply terminals (VDD1,GND1) to receive a first power supply voltage applicable between said terminals (VDD1,GND1) and also comprising an output terminal (ou1);
- a second circuit environment (CE_2) made from said substrate, comprising a second pair of power supply terminals (VDD2,GND2), distinct from said first pair of terminals (VDD1,GND1), to receive a second power supply voltage applicable between terminals of said second pair and also comprising an input terminal (In2) electrically coupled with said output terminal (Ou1). The integrated circuit comprises a device for protecting from electrostatic discharges comprising an integrated resistive device (Rcd) connected between said output terminal (Ou1) and said input terminal (In2).
