Stresses beyond those listed under “absolute maximum ratings”

may cause permanent damage to the device. These are stress

ratings only, functional operation of the device at these or any

other conditions beyond those indicated under “recommended

operating conditions” is not implied. Exposure to absolute

maximum-rated conditions for extended periods may affect device

reliability.
