Fault Protection

TI’s multiplexer portfolio includes many different configurations of fault protected multiplexers that can be utilized to prevent any damage from high common mode events. Most of these types of devices include ± 60V fault protection, fault reporting, and programmable fault detection which can prove to be invaluable for such situations where there are possibilities of these high common mode voltages existing. Lastly, given these features inherent in TI's fault protected multiplexers, this eliminates the need for external components such as current limiting resistors and diodes to provide protection to the signal chain.
