Hello,
Yes your understanding is correct. Ultimately, the difference in voltage should not be more than 40 volts maximum.
Thanks and regards,

Dear AZIZ,
Thank you for replied.
For point 3, if the VEE2 reference to 0V and the Absolute voltage VCC2 rating is shift -8.3V to 32V, right? I there any other parts I haven't considered?
