I want to detect voltage between 10V and 260V AC / DC, I have thought to use the HCPL-3700 but if I put the 47k resistors the output is activated, but if I apply 12V the output is not activated.
schematic
Does anyone know if it can be done with this chip, or does this one not work and I have to use another type?
Basically I want to activate a 5Vdc PIC with whatever voltage is applied. I don't need zero crossings or anything special, only that it be activated with that input voltage range.
Any ideas?

Thank you very much
