Note: Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
those or any other conditions, above those indicated in the
operational listings of this specification, is not implied. Expo-
sure to maximum rating conditions for extended periods may
affect device reliability.
