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 an appropriate logic voltage level
(Ground to VDD_IO).
3. No heat spreader (HS) in this package. The θJC/θJA is under air velocity 0m/s.
4. IVDD_A3.3 measured at pin 9. IVDD_IO measured at pins 21, 30, and 56. IVDD_AL measured at pins 6 and 16. IVDD_DL measured at pins 40 and 51.
5. TA = 25°C. Specification for packaged product only.
