Notes:
1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. PD(max) = (TJ(max) – TA) / θJA, where θJA, depends upon the printed circuit layout. See “Applications Information.”
4. Device is ESD sensitive. Handling precautions recommended.
5. Specification for packaged product only.
