Absolute Maximum Ratings
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.

The input voltage range 36…75 Vdc meets
the European Telecom Standard prETS
300 132-2 Nominal input voltage range in
48 V and 60 Vdc power systems,
–40.5…–57.0 V and –50.0…–72.0 V
respectively. Absolute max continuous input
