Address / Command Setup, Hold and Derating
For all input signals the total tIS (setup time) and tIH (hold time) required is calculated by adding the data sheet tIS (base)
and tIH (base) value (see Table 11) to the ΔtIS and ΔtIH derating value (see Table 12) respectively. Example: tIS (total
setup time) = tIS (base) + ΔtIS
Setup (tIS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of V

For a valid transition the input signal has to remain above/below V
