3.0 ELECTRICAL CHARACTERISTICS
3.1 Absolute Maximum Ratings
Stresses beyond those listed under this section may
cause permanent damage to the device. These are stress
ratings only and are not tested. Functional operation of
the device at these or any other conditions beyond those
indicated in the operational sections is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
