Note a:
Stresses greater than those listed under “Absolute Maximum Rat-
ings” may cause permanent damage to the device. This is a stress
rating only, and functional operation of the device at conditions
above those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.
