NOT RECOMMENDED FOR NEW DESIGNS TRIPLE DIFFERENTIAL 2:1 MULTIPLEXER SY10E457 SY1S0YE10405E7457 SY100E457 FEATURES s Differential D and Q s Extended 100E VEE range of –4.2V to –5.5V s VBB output for single-ended use s 700ps max. propagation delay s High frequency outputs s Separate and common select s Internal 75KΩ input pulldown resistors s Available in 28-pin PLCC package 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.
