1. Within-device skew is defined as identical transitions on similar paths through a device.

2. Duty cycle skew is defined 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.

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 VPPmin and 1V. The lower end of the CMR range varies 1:1 with VEE. The

numbers in the spec table assume a nominal VEE = –4.5V. Note for PECL operation, the VCMR(min) will be fixed at 5.0V – |VCMR(min)|.
