NOTE: Stresses greater than 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 speci-
fication is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect reliability.
