Caution The recommended operating range may be exceeded without causing any problems provided
that the absolute maximum ratings are not exceeded. However, if the device is operated in a way
that exceeds the recommended operating conditions, the margin between the actual conditions
of use and the absolute maximum ratings is small, and therefore thorough evaluation is
necessary. The recommended operating conditions do not imply that the device can be used
with all values at their maximum values.
