Frequent questions

  • [FAQ] How do Overvoltage & Fault protected devices work and which devices have this feature?

    What are Overvoltage & Fault events? An overvoltage or fault event is when a signal with a voltage greater than the maximum rating of the analog switch or multiplexer is fed into the device. These events can occur for many reasons such as EMI from…

  • [FAQ] What Analog Switch/Multiplexer should I use for MIPI applications?

    Mobile Industry Processor Interface (MIPI) is a protocol primarily used for high speed interfacing by smart phones, cameras, tablets, displays, and many other devices. A MIPI system consists of data line groups called lanes which work together to create…

  • [FAQ] What is the Off Resistance of an Analog Switch / Multiplexer?

    Other Parts Discussed in Thread: TMUX1574 What is the Off Resistance of an Analog Switch / Multiplexer? Off resistance of a switch / multiplexer is the resistance seen between a drain and source channel when the device is powered on (V CC = typical supply…

  • [FAQ] What is Charge Injection?

    Other Parts Discussed in Thread: MUX36S08 What is Charge Injection? Charge injection (Q INJ ) is the coupling of the switch control signal through some parasitic capacitance. The charge present from this parasitic capacitance is then injected into the switch…

  • [FAQ] How Can I Reduce the Click and Pop Noise on my Audio Switch and Detection Jack?

    Part Number: TS5A22364 What are Click and Pop Noises? Click and pop noises occur when a step DC voltage is switched into the speaker. This DC voltage is heard as an audible “click” or “pop” from the output of the speaker. The…

  • [FAQ] What are the Types of Architectures TI Switches and Multiplexers Use and how do I know which one my device has internally?

    Introduction TI switches and multiplexers are often designed using one of three different circuit architectures that enable different characteristics and capabilities depending on which one is selected. The typical architectures can be broken down into…

  • [FAQ] Do TI Analog Switches/Multiplexers have Internal ESD Protection?

    Other Parts Discussed in Thread: SN74CB3Q3345 While all TI switches and multiplexers incorporate some type of ESD protection, the way they are implemented can differ significantly. The typical implementation can be seen below (simplified model): In this…

  • [FAQ] What do the top side markings mean for TI analog switches & multiplexers?

    TI devices typically have a code printed or etched on their top side that contains information about what device it is, when it was manufactured, and where it was manufactured. This code is referred to by a few names such as top marking, top side marking…

  • [FAQ] What does the G3/G4/E4 suffix mean on TI analog switches & multiplexers?

    Some TI switches and multiplexers have orderable part numbers labelled with an E4/G4/G3 suffix. There is no difference between a device labeled with an E4/G4/G3 suffix and one without the label. TI.com highlights this in the ordering & quality section…
