18. tIS and tIH (input setup and hold) derating
1) Input waveform timing is referenced from the input signal crossing at the V_IH(AC) level for a rising signal and V_IL(AC) for a falling signal applied to
the device under test.
2) Input waveform timing is referenced from the input signal crossing at the V_IH(DC) level for a rising signal and V_IL(DC) for a falling signal applied to
the device under test.
