The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must
not be exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be
irreparably altered and the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation
in other equipment. Applications using the device should be designed so that no absolute maximum rating
will ever be exceeded under any operating conditions.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set
forth in this document.
