Although the total setup time for slow slew rates might be negative (for example, a valid
input signal will not have reached V
tion), a valid input signal is still required to complete the transition and to reach V

between the values listed in Table 56 on page 78 and Table 57 on page 79, the derating
values may be obtained by linear interpolation.

the nominal slew rate line anywhere between the shaded “V
