Note 1. Stresses above 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 condition above 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.
