Notes:
1. Differential input voltage required to obtain a full ECL swing on the outputs.
2. VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the input signals are within the VCMR range
and the input swing is greater than VPP (min.) and <1V.

Notes:
1. Within-device skew is defined as identical transitions on similar paths through a device.
2. Duty cycle skew guarantee holds only for differential operation when the delays are measured from the cross point of the inputs to the cross point of the
outputs.
3. Minimum input swing for which AC parameters are guaranteed.
