Notes:
1.The numbers in this table are tested using the methodology presented in Table 25 and are based on the operating conditions set forth in Table 7 and Table 10.
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 21.
