Part Number: TS3A44159

Do we have a low capacitance version of TS3A44159 in same footprint? The COM pin capacitance is 164 pf but I am looking for something with 10 times less capacitance

  • Hello,

    What are you looking for when you say footprint? We do not have a device that is pin-to-pin compatible with TS3A44159, however we have options with the same size & package.

    TMUX1574 is a great device that has a typical source/drain on capacitance of 7.5pF. TMUX1574 is available in the same packages (TSSOP, UQFN) as TS3A44159. What package are you looking for?

    What is your application and end equipment for this device? TMUX1574 has a significantly higher bandwidth and wider signal range. In addition, TMUX1574 includes powered-off protection, which protects the system and device when the supply voltage is 0V. 

    Let me know what you think about TMUX1574.

    Best regards,

    Saminah
