DESCRIPTION
The SY10/100E457 are 3-bit differential 2:1
multiplexers. The fully differential data path makes the
devices ideal for multiplexing low skew clock or other
skew sensitive signals. Multiple VBB 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.
