*
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of
time may affect device reliability.
include all overshoots due to system and/or tester noise.
Do not attempt to test these values without suitable equipment.
