Note:
1. Stresses beyond "Absolute Maximum Ratings" may cause permanent device damage. Continuous exposure to absolute
maximum rating conditions may affect device reliability. Functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of the specification is not implied.
