4.6.1. Absolute Maximum Ratings
Stresses beyond those listed in the “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 “Recommended Operating Conditions/Characteristics” of this specification is not implied. Exposure to absolute
maximum ratings conditions for extended periods may affect device reliability.
