t
crossing of V
a falling signal is defined as the slew rate between the last crossing of V
first crossing of V
If the actual signal is always earlier than the nominal slew rate line between shaded

If the actual signal is later than the nominal slew rate line anywhere between the sha-

AC level to DC level is used for the derating value (see Figure 23 (page 58)).

Although the total setup time might be negative for slow slew rates (a valid input signal
will not have reached V
input signal is still required to complete the transition and reach V
For slew rates in between the values listed in Table 29 (page 56) and Table 30
(page 57), the derating values may obtained by linear interpolation.
