NOTES: (1) CAUTION: Stresses listed under “Absolute Maximum Ratings” may be applied to devices one at a time without causing permanent
damage. Functionality at or above the values listed is not implied. Exposure to these values for extended periods may affect device reli-
ability.
(2) Vitesse guarantees the functional and parametric operation of the part under “Recommended Operating Conditions” except where
specifically noted in the AC and DC Parametric tables.
