ELECTRICAL SPECIFICATION
Important Note: The "Absolute Maximum Ratings" are stress ratings only, and functional operation of the device at conditions other
than those indicated in the "Operating Conditions" sections of this specification are not implied. Exposure to the absolute maximum
ratings for an extended period may reduce the reliability or useful lifetime of the product.
