Note: Stresses greater than 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 conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
