Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond
the Recommended Operating Ranges limits may affect device reliability.
4. Backfeed Voltage can not be guaranteed for junction temperature in excess of 85°C. See V in Electrical Characteristics Table.
