Note 1:

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).
