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, Table 10, and Table 12.

2.These adjustments are used to convert output- and three-state-path times originally specified for the LVCMOS25 standard with 12 mA drive and Fast slew rate to times that correspond to other signal standards. Do not adjust times that measure when outputs go into a high-impedance state.
