Fig d.)
Although for slow slew rates the total setup time might be negative(i.e. a valid input signal will not have reached VIH/IL(ac) at the time
of the rising clock transition) a valid input signal is still required to complete the transition and reach VIH/IL(ac).
For slew rate in between the values listed in table x, the derating valued may obtained by linear interpolation.
These values are typically not subject to production test. They are verified by design and characterization.
