ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are limiting values of permitted operation and should never be
exceeded under the worst possible conditions either initially or consequently. If exceeded by
even the smallest amount, instantaneous catastrophic failure can occur. And even if the
device continues to operate satisfactorily, its life may be considerably shortened.
