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.
