Absolute Maximum Ratings
Operating Range
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, in which case 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 maximum rating will ever be exceeded under
any operating condition.
