Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating. Unused inputs must always be tied to a appropriate logic voltage level (Ground
to VDD_IO).
3. No (HS) heat spreader in this package. The θJC/θJA is under air velocity 0m/s.
