Note:
Operation at levels greater than those listed under
“Absolute Maximum Ratings” may cause perma-
nent damage to the device. This is a stress rating
only; functional operation of the device at these or
any other conditions above those indicated in the
Operation Condition tables is not implied. Expo-
sure to Absolute Maximum Rating conditions for
extended periods may affect reliability.
