Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maximum Stress
Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at
these conditions or conditions greater than those defined in the operational sections of this data sheet is not implied. Expo-
sure to absolute maximum stress rating conditions may affect device reliability.)
