Stress in excess of Absolute Maximum Ratings may cause permanent damageꢀ 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 Characteristicsꢀ
If exposed to stress above these limits, function and performance may degrade in an
unspecified mannerꢀ
