can operate normally and maintain constant product quality. If a product is used with operating conditions
that exceed even one of the Recommended Operating Conditions, the product may malfunction. Always
be sure to design your application devices so they will operate within the range of the Recommended
Operating Conditions.
The Absolute Maximum Rating is a rating that must never be exceeded, even for an instant. Not a
single Absolute Maximum Rating value can be exceeded. If any Absolute Maximum Rating value is
exceeded, the product may be damaged or weakened, or damage or combustion may cause
personal injury. Always be sure to design your application devices so the Absolute Maximum
Rating is never exceeded.
Even be sure that VDD33 + 0.3 V does not exceed the maximum rating for VDD33
Even be sure that VDD25 + 0.3 V does not exceed the maximum rating for VDD25
