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.
ORDERING INFORMATION
See detailed ordering and shipping information in the package
dimensions section on page 4 of this data sheet.
Preferred devices are recommended choices for future use
and best overall value.
