* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions
beyond those indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is not implied.
1. Output in HIGH or LOW State. IO absolute maximum rating must be observed.
