3.2 DC & AC Logic Input Levels
3.2.1 Input DC Logic Level
3.2.2 Input AC Logic Level
3.2.3 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 VIL(ac) to VIH(ac) on the positive transitions
