Note1.Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2.The device is guaranteed to meet performance specification within 0℃~+70℃ operating temperature range
and assured by design from -20℃~+85℃.
