The absolute maximum ratings of a semiconductor device are a set of specified parameter values, which must not
be exceeded during operation, even for an instant. If any of these rating would be exceeded during operation, the
device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no
longer be guaranteed. Moreover, these operations with exceeded ratings may cause break down, damage and/or
degradation to any other equipment. Applications using the device should be designed such that each absolute
maximum rating will never be exceeded in any operating conditions. Before using, creating and/or producing
designs, refer to and comply with the precautions and conditions set forth in this documents.
