Hi,

Is it possible to use ISO1541 as isolator for I2C line under conditions of VCC1=3.3V, GND1=0V, VCC2=0V, GND2=-5V?

I have found the following URL and assume that it can be used under these conditions.

Best Regards,

Nishie

Short answer is Yes. You can find the explanation already in the referred e2e above.

If you still need any further clarification on the supply voltage, let us know.
