Absolute Maximum Ratings*
Stresses at or 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 these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions may affect
device reliability.
