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 in the Electrical Specification. If exposed to stress above these limits, function and performance
may degrade in an unspecified manner.
Note 1: Isolation voltage (input/output to base-plate) max 750 Vdc.
*) Apply for the narrow input version VI= 40-60 V.
