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.
