Notes:
1.
For Max or Min conditions, use appropriate value specied under Electrical Characteristics for the applicable device.
2.
Minimum limits are guaranteed but not tested on Propagation Delays.
3.
This parameter is guaranteed but not production tested.
4.
Skew between any two outputs, of the same package, switching in the same direction.
This parameter is guaranteed by design.
