Notes:
1. See test circuit and waveforms.
2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Skew between outputs of the same bank and same package, switching in the same transition.
4. Skew between outputs of all banks of the same package with A1 through A8 tied together, switching in the same transition.
5. This parameter is guaranteed but not production tested.
