Caution If even one of the parameters exceeds its absolute maximum rating even momentarily, the quality
of the product may be degraded. The absolute maximum rating therefore specifies the upper or
lower limit of the values at which the product can be used without physical damage. Be sure not to
exceed or fall below these values when using the product.
