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
REF
level applied to the device
under test.
2. The input signal minimum slew rate is to be maintained over the range from V
REF
to V
IH(ac)
min for rising
edges and the range from V
REF
to V
IL(ac)
max for falling edges as shown in the figure below.
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.
