Table 4. Absolute Maximum Ratings(1)
1. Absolute maximum continuous ratings are those maximum 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 at absolute-maximum-rated
conditions is not implied.
