故障保护保存多路复用器，开关和下游电路

故障，当施加电压开关输入，MUX，或信号线电路保护电压超过电源引脚。更实用的方法，故障保护，故障保护开关，多路复用器，信号线电路保护员工。本应用笔记讨论了几种方法融入开关和多路复用器故障保护。Maxim>AppNotes>SWITCHESANDMULTIPLEXERSKeywords:faultprotection,faultprotected,analogswitches,multiplexers,muxesJun26,2002APPLICATIONNOTE1132FaultProtectionSavesMultiplexers,Switches,andDownstreamCircuitryAbstract:Discretecomponentsareavailabletoprotectagainstfaultscausedwhenavoltageappliedtotheinputofaswitch,mux,orsignal-linecircuitprotectorexceedsthevoltageatthepowersupplypins.Amorepracticalapproachtofaultprotectionemploysfault-protectedswitches,multiplexers,andsignal-linecircuitprotectors.Thisapplicationnotediscussesseveralapproachesthatintegratefaultprotectionintoswitchesandmultiplexers.Aninputfaultconditionoccurswhenavoltageappliedtotheinputofaswitch,mux
