Caution
Product quality may suffer if the absolute maximum rating is exceeded for even a single parameter
even momentarily. That is, the absolute maximum ratings are rated values at which the product is
on the verge of suffering physical damage, and therefore the product must be used under conditions
which ensure that the absolute maximum ratings are not exceeded.
