*Stresses above those listed under "Absolute Maximum Ratings" may
cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions above
thoseindicatedintheoperationsectionsofthespecificationsisnotimplied.
Exposure to Absolute Maximum Rating conditions for extended periods
may affect device reliability.
