multiplexers. The fully differential data path makes the
devices ideal for multiplexing low skew clock or other
skew sensitive signals. Multiple V
BB
pins are provided to
ease AC coupling input signals.
The higher frequency outputs provide the device with
a >1.0GHz bandwidth to meet the needs of the most
demanding system clock.
Both separate selects and a common select are
provided to make the device well suited for both data
path and random logic applications.

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