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 V
DD).
3.
No heat spreader in package.
4.
Specification for packaged product only.
5.
Measurements were taken within operating ratings.
