*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 or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to the absolute maximum rating conditions for extended period may affect device
reliability.
