Note 1. Maximum ratings are those values beyond which device damage can occur. Maximum ratings
applied to the device are individual stress 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.
