About PCF8583 INT 

 

I am using PCF8583 INT pin function to power on the system.The pull up resistor is 3.3K,and pull up voltage is 14.4V,so the PCF8583 has an alarm,the current flow over INT is about 4.3mA.The system seems work fine for a long time until one day I noticed that in the datasheet the maxium voltage on INT pin of PCF8583 is 6V.

Is it OK if I continue use the 14.4 pull on voltage?

 

Thank you.
