Table 8: Absolute maximum ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only. Functional operation of
the device at these or any other conditions beyond those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
