Notes:
1. Skew is measured between outputs under identical transitions.
2. Minimum input swing for which AC parameters are guaranteed. The device has a DC gain of ~40.
3. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified
range and the peak-to-peak voltage lies between VPP min. and 1V.
