Note :
1. For information related to V
7.5 AC Input Test Conditions
Note :
1. Input waveform timing is referenced to the input signal crossing through the V
2. The input signal minimum slew rate is to be maintained over the range from V
3. AC timings are referenced with input waveforms switching from V
