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. Input Ratings T < T C C(MAX) Characteristic Description Conditions Min. Typ. Max.
