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

2. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device.

3. Minimum input swing for which AC parameters guaranteed. The device will function properly with input swings below 200mV, however, AC

delays may move outside of the specified range. The device has a DC gain of

≈40.

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 number

in the spec table assumes a nominal VEE = –3.3V. Note for PECL operation, the VCMR(min) will be fixed at 3.3V – |VCMR(min)|.
