1) Input waveform timing is referenced to the input signal crossing through the VREF level applied to the device under test.
2) The input signal minimum Slew Rate is to be maintained over the range from VIH(ac).MIN to VREF for rising edges and the range from VREF to
IL(ac).MAX for falling edges as shown in Figure 4
V
3) AC timings are referenced with input waveforms switching from VIL(ac) to VIH(ac) on the positive transitions and VIH(ac) to VIL(ac) on the negative
transitions.
