IR2110 and Vcc Vdd COM relationship
Use the recommended operating conditions, not the absolute maximum ratings.

When it says Vcc, Vss, Vdd, etc. in the "Absolute Max Rating" table, it does not mean the actual value being used. It means the worst case value in that same table. They are constants in that table, not variables.

So when you insert actual values being used into expressions in the "Absolute Max Rating" table, you get nonsensical results.

This is unlike the the "Recommended Operating Conditions" table where they are variables for the actual values being used.
