* Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Absolute

Maximum Ratings are limited values applied individually while

other parameters are within specified operating conditions,

and functional operation at any of these conditions is NOT

implied. Device performance and reliability may be impaired by

exposure to absolute rating conditions for extended periods of

time.
