Abstract
The invention concerns an integrated circuit comprising means of delivering, on at least one output, a predetermined output voltage representative of a logic level, means of distributing a mains voltage and means of generating an internal voltage reference lower than the mains voltage, comprising means of connecting the mains voltage to the output and means of limiting and/or detecting the voltage at the output at the predetermined output voltage value, taking into account the reference voltage.
