Electrical Characteristics
Absolute Maximum Ratings
Stresses greater than the Absolute Maximum Ratings listed in Table 36 may
cause permanent damage to the device. This rating is a stress rating only. Func-
tional operation of the device at any condition above those indicated in the opera-
tional sections of these specifications is not implied. Exposure to absolute
maximum rating conditions for an extended period may affect device reliability.
