PIN DESCRIPTIONS
ABSOLUTE MAXIMUM RATINGS
Note:
1. Absolute Maximum Ratings are threshold limit values that must not be exceeded.
2. Operation above these absolute maximum ratings may cause degradation or permanent damage to the device.
3. These are stress ratings only and do not necessarily imply functional operation below these limits.
