MAXIMUM RATINGS
Maximum ratings are those values beyond which device damage can oc-
cur. 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.
