TMUX6136: Rds on 120 Ω

Part Number: TMUX6136
Other Parts Discussed in Thread: TMUX6111, MUX508, MUX36S08

hi sir

may i know why the TMUX6136 rdson is  120 Ω

i see the ADI/ADG1613 only have 1Ω

or TMUX6136 have any key feature to fighting ADI/ADG1613?


  • Hi Alex,


    The ADG1613 is a quad SPST switch, so our closest part is the TMUX6111/2/3 Families of parts. They have the same pinout, but it also has a higher Ron. 

    The TMUX6111/2/3 Family of parts can handle higher dual voltages than the ADG1613. 

    What application are you looking at, and do you need a Pin to Pin replacement for the ADG1613?  What do your Rails look like for the application?

    The TS12A44514  is a quad SPST switch as well that has a similar on resistance and can perform at the same supplies, if the ADG1613 isn't using a negative voltage supply (VSS = 0V). 


    Please let me know, so we can find you the best part.

  • HI SIR

    Do you have the competive table between ADG1613 & TMUX6111/2/3

    if the rds on is high, it mean will  hot in the switch on during current across?right?

    i use the ADG1613 to switch power source

    and, do you have any parts to replace ADG1414,thanks

  • Hi Alex,

    All Parameters in TAN refer to Recommended Operating Conditions and/or Absolute Maximums.

    Due to the differences in power supply ranges and available data we have parameters in PINK referring to the 12V single supply table, the only comparable data points we have for the parts. 

    GREEN indicates  best performance for that category

    RED indicates worst performance for that category

    YELLOW indicates similar performance for that category

    BLUE indicates Not enough Data for Comparison or Usage Impacts Parameter Too much for Fair Comparison

    ORANGE indicates that the power ranges do not have very much overlap

    If a box contains the word "or" and it is not BLUE it means that this spec is package dependent and will change based on which package you choose. 

    If a box contains the word "or and it is BLUE that means that operating conditions influence parameter greatly

    Ultimately yes, a higher Ron would lead to higher amount of heat production for the same current, if the load you are powering is high impedance, i.e. low current, the heat production between 1 Ohm and 230 Ohms is typically negligible. 

    What is output current for the power supply? I would be worried it would be greater than 30 mA, which this switch could support. Most of the analog switches we have our signal switches and typically lower current.

    We do have specific Power Muxes that can support higher currents if the 30 mA is not going to be enough for the application.

    For the ADG1414 we don't have any pin to pin matches because we don't have SPI controlled Muxes. The best parts that we have that are close to the ADG1414 is the MUX508  or if you want one that has slightly better specs the MUX36S08. Once again these parts have higher typical Ron's than the ADG1414, but the MUX508 and MUX36S08 have better specs when it comes to parameters such as leakage.
