NOTES:

1. Parametric values specified at:

5 volt Power Supply Range 100S838 Series: -4.2V to -5.5V.

3 volt Power Supply Range 100S838L Series -3.0V to -3.8V.

2. Skew is measured between outputs under identical transitions.

3. Minimum input swing for which AC parameters are guaranteed. The device will function reliably with differential inputs down to 100mV.

4. 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 1.0V. The lower end of the CMR range is dependent on VEE and is equal to VEE +1.65V.
