Note1. Stresses listed as the above "Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to maximum rating conditions for extended periods may
remain possibility to affect device reliability.
Note2. It’s guaranteed by design and functionally tested during production manufacture.
