Notes:

Exceeding the absolute maximum rating may damage the device.

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).

No (HS) heat spreader in this package. The

JC/θJA is under air velocity 0m/s.

TA = 25°C. Specification for packaged product only.
