Input waveform timing is referenced to the input signal crossing through the V
under test.
The input signal minimum slew rate is to be maintained over the range from V
and the range from V
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.
