Note1: Absolute Maximum Ratings are threshold limit values that must not be exceeded even for an instant under any

condition. Moreover, such values for any two items must not be reached simultaneously. Operation above these absolute

maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only and do not

necessarily imply functional operation below these limits.
