Caution

Even if 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 value at which the product can be used without physical damages. Be sure

not to exceed or fall below this values when using the product.
