Absolute Maximum Ratings
Thermal Data
Stress in excess of Absolute Maximum Ratings may cause permanent
damage. Absolute Maximum Ratings, sometimes referred to as "no
destruction limits," are normally tested with one parameter at a time
exceeding the limits of output data or electrical characteristics. If exposed
to stress above these limits, function and performance may degrade in an
unspecified manner.
