Caution Product quality may suffer if the absolute maximum rating is exceeded for even a single
parameter or 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.
