* Notice: Stresses above those listed under "Maximum Rat-
ings" 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 sections of this specification is not intended. Expo-
sure to maximum rating conditions for extended periods may
affect device reliability.
