Caution Product quality may suffer if the absolute rating is exceeded for any parameter, even momen-
tarily. In other words, an absolute maxumum rating is a value at which the possibility of psysical
damage to the product cannnot be ruled out. Care must therefore be taken to ensure that the
these ratings are not exceeded during use of the product.
