SY100E457 TRIPLE DIFFERENTIAL SY10E457 SY100E457 2:1 MULTIPLEXER FEATURES DESCRIPTION Differential D and Q The SY10/100E457 are 3-bit differential 2:1 multiplexers. The fully differential data path makes the Extended 100E VEE range of 4.2V to 5.5V devices ideal for multiplexing low skew clock or other VBB output for single-ended use skew sensitive signals. Multiple VBB pins are provided to 700ps max. propagation delay ease AC coupling input signals. High frequency outputs The higher frequency outputs provide the device with a >1.0GHz bandwidth to meet the needs of the most Separate and common select demanding system clock. Internal 75K input pulldown resistors Both separate selects and a common select are Available in 28-pin PLCC package provided to make the device well suited for both data path and random logic applications.
