Note:

Stresses greater than those listed under

MAXIMUM RATINGS may cause perma-

nent 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 may affect reliability.
