These parameters are asynchronous events not related to any internal clock edge.
These parameters are characterized but not tested.
Data in "Typ" column is at 5V, 25˚C unless otherwise stated. These parameters are for design guidance only and are not
tested.
Note: Refer to Figure 23-1 for load conditions.
