Note 1:
2:
Parameter is characterized but not tested.
Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are not tested.
Required output enable filter high time must account for input path analog delays (= TOEH - TDR + TDF).
Required output enable filter low time must account for input path analog delays (= TOEL + TDR - TDF).
