Abstract

Passing a signal through multiple multiplexers, often called cascading, is a useful way to create new and creative designs for complex system needs. While using this technique does allow for more flexibility in design it is important to note the effects of multiplexer parasitics as more multiplexers are added to the bus. This document will expand on the effects of accumulate On-Resistance, On-Capacitance and On-Leakage when cascading multiplexers while also showing both simulated and bench results of the impact on insertion loss. A table of recommended devices for cascading applications is highlighted at the end of the document.
