NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

INGS may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other condi-

tions above those indicated in the operational sections of this specifica-

tion is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect reliability.
