NOTICE

Absolute maximum ratings are the extreme limits the device will momentarily withstand without damage to the device. Electrical

and mechanical characteristics are not guaranteed if the rated voltage and/or currents are exceeded, nor will the device

necessarily operate at absolute maximum ratings.
