Slew Rate Definition for Input and Data Setup and Hold Times
Setup (tIS & tDS) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VIH(dc)min
and the first crossing of VIH(ac)min. Setup (tIS & tDS) nominal slew rate for a falling signal is defined as the slew rate
between the last crossing of VIL(dc)max and the first crossing of VIL(ac)max, (fig. A) If the actual signal is always earlier
than the nominal slew rate line between shaded dc to ac region, use nominal slew rate for derating value. If the actual
signal is later than the nominal sl
ew rate line anywhere between shaded dc to ac region, the slew rate of a tangent line to
the actual signal from the ac level to dc level is used for derating value.(fig.B)
Hold (tIH & tDH) nominal slew rate for a rising signal is defined as the slew rate between the last crossing of VIL(dc)max
and the first crossing of Vref. Hold (tIH & tDH) nominal slew rate for a falling signal is defined as the slew rate between the
last crossing of VIH(dc)min and the first crossing of Vref.(fig. A). If the actual signal is always later than the nominal slew
rate line between shaded dc to Vref region, use nominal slew rate for derating value. If the actual signal is earlier than the
nominal slew rate line anywhere between shaded dc to Vref region, the slew rate of a tangent line to the actual signal from
the dc level to Vref level is used for derating value.(fig.B)
