Figure 3: Absolute Maximum Ratings
Stresses above those listed may cause permanent
damage to the device. This is a stress rating only and
functlonal operation of the device at these condltions,
or at any other condition above those indicated in the
operations section of this specification, is not Implied
Exposure to absolute maxlmum rating conditions for
extended perlods may affect device reliability.
