1. Respecting the above limits prevents potential damage to the isolation barrier upon failure on logic or process side circuitry.

The user should apply these values to protect the IC and ensure the safety of the embedded isolation barrier. LOGIC(x)

stands for any pin on the logic side; OUT(x) stands for any of the 8 output pins on the process side.
