1. Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Extended exposure to these

conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute maximum−rated

conditions is not implied.

2. Tested to EIA/JESD22−A114−A.

3. Tested to EIA/JESD22−A115−A.

4. Tested to JESD22−C101−A.
