Note 1. 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℃.
