Electrical Characteristics
Absolute Maximum Ratings
Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating
only, and the functional operation of the device at these, or any other conditions above those listed in the operational section of the
specification, is not implied. Exposure to conditions at absolute maximum ratings for extended periods may affect device reliability.
