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 maximum rating will never be exceeded in any operating conditions.

13. Operating Ranges
The absolute maximum ratings of a semiconductor device are a set of specified parameter values, which must not
If any of these rating would be exceeded during operation, the device electrical characteristics may be irreparably
