Note 1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only; 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 absolute maximum rating conditions for extended periods may affect device reliabilit.

1). JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
2). JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
