Maximum ratings are those values beyond which device damage can occur.

Maximum ratings applied to the device are individual stress limit values (not

normal operating conditions) and are not valid simultaneously. If these limits are

exceeded, device functional operation is not implied, damage may occur and

reliability may be affected.
