Stresses greater than those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the de-
vice. This is a stress rating only; operation of the device at
any condition above those indicated in the operational sec-
tions of these specifications is not implied. Exposure to ab-
solute maximum rating conditions for extended periods
may affect device reliability.
