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.
The Micrel SY10E457 and SY100E457 are 3‑bit differential 2:1 multiplexers offering a fully differential data path, low propagation delay, and high‑frequency operation up to >1.0 GHz. The handbook provides feature descriptions, pin configuration, and detailed DC and AC electrical characteristics.
Key sections include a pin‑out diagram, DC and AC electrical parameters such as VEE output reference voltage, propagation delay, power‑supply current, and ordering codes for commercial packaging. Mechanical dimensions and package drawings are also supplied.
