NOTES: (1) CAUTION: Stresses listed under “Absolute Maximum Ratings” may be applied to devices one at a time without caus-
ing permanent damage. Functionality at or above the values listed is not implied. Exposure to these values for extended
periods may affect device reliability.
(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
