ABSOLUTE MAXIMUM RATINGS

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

specification is not implied. Exposure to absolute maxi-

mum rating conditions for extended periods may affect

reliability.
