Stresses above those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent device failure. Functionality
at or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device
reliability. Operating ranges define those limits between which the functionality of the device is guaranteed.
