Table 8: Absolute Maximum Ratings
Stresses above those listed may cause permanent damage to
the device. This is a stress rating only and functional operation
of the device at these conditions, or at any other condition
above those indicated in the operations section of this
specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliabillty.
