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 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. No terminal voltage may exceed
