Maximum ratings are those value beyond which device damage con occur. Maximum ratings applied to the device
are individual stress limit values (not normal operating conditions) and are not valid simultneously.
If these limits are exceeded, device functional operation is not implied, damage may occur and reliablilty
may be affected.
