The numbers in this table are tested using the methodology

set forth in
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.
