Notes:
1.
The numbers in this table are tested using the methodology presented in Table 27 and are based on the operating conditions set forth in
2.
This propagation time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the data Input. When this is
true, add the appropriate Input adjustment from Table 23.
