Bus Switches for Speed, Safety, and Efficiency: What They Are and What You Should Know About Them.
Bus switches are characterized by sub-nanosecond propagation delay and fast switching, and are designed for connecting to high-speed digital buses. They are ideally suited for voltage translation, hot swapping, hot plug, bus- or capacitance isolation, and many other applications. The key features that make them suitable for so many different applications include low on-resistance, low capacitance, and low propagation delay. -
