TS3A5018: What is the max switching time for the TS3A5018?

Part Number: TS3A5018
Other Parts Discussed in Thread: TMUX1574,

E2E,

I am now doing some stress testing on TS3A5018RSVR  EVM so that switch frequently changes status (repeating on/off).

 

Do you have data/information that is the maximum switching times of the switch?  the switch frequently changes status means (repeating process of changing NC and NO)

 

Thank you,

Adam

 

  • Hi Adam,

    Thanks for your question. For this device, the transition time (or switching time) can be found as turn-on time (tON) and turn-off time (tOFF) in the switching characteristics tables. In this case**, tON/tOFF is the time taken for the switch to react to a change in logic input, IN or /EN. You can find the minimum, typical, and maximum tON/tOFF time according to supply voltage in sections 6.9, 6.10, 6.11 of the datasheet. Check out the figure below to learn about the test setup for this characteristic.

    What is the customer's application/end equipment? I would like to suggest taking a look at TMUX1574 if you are interested in a device with lower Ron, lower leakage current, higher bandwidth, and more features, such as powered-off protection and 1.8V logic compatibility.

    Let me know if you have any additional questions!

    Regards,

    Kate

    **Take note that transition time may be indicated by a separate characteristic, Ttran, in datasheets for other devices. To learn more about timing characteristics, watch this video!

  • Hi Kate,

    Thanks for prompt reply and your feedback is great.

    Customer would like to know will be like switch reliability/life testing, and customer would like to know the life(times) of switch change NC and NO.

    Please advise.

  • Hi SHH,

    Are you interested in the reliability information for TS3A5018 or TMUX1574?

    For any device, you can find quality and reliability information in the product folder in the "Quality & packaging" tab. The information is organized according to package. I've included a screenshot of the table for TMUX1574, view the information for TMUX1574 by following this link to the product folder

    From this table, you can access the Qualification Summary and reliability monitoring tables.

    TS3A5018 quality & packaging information can be found here.

    Reliability terminology, testing, and other general informational resources are located here.

    Take a look and let me know if you find the information you need.

    Best regards,
    Kate

  • Hi Kate,
    Thanks for the information, but it seems there is no information that mentions how maximum (switch)times are. Please advise.

  • Hi SHH,

    Thank you for the clarification. 

    We do not collect this information/data because device failure is not related to number of electrical connections/disconnections. The number of contacts is certainly a concern with devices such as electro-mechanical relays, but for TI's electrical switches and multiplexers, this should not be an indicator of device lifetime.

    TI performs High Temperature Operating Life (HTOL) per JESD22-A108, which helps determine a device’s intrinsic reliability by simulating operation and aging over its’ lifetime. The qualification report shows x3 lots passed HTOL testing at 125C for 1000hrs, which is equivalent to approximately 9 years of use at 55C.

    As a reminder, it is important to maintain switch operation within the Recommended Operating Conditions, as exposure to Absolute Maximum conditions and beyond may affect device reliability or damage the device.

    Best regards,
    Kate

  • Hi Kate,

    if the switch on/off cycle is over 100k times within 6 month, is that ok for TS3A5018 itself?

  • Hi SHH,

    Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. You can find both Absolute Maximum Ratings and Recommended Operating Conditions in the datasheet.

    As I mentioned before, number of switch "cycles" or number of switches is not related to device reliability of electrical switches as long as operation within recommended operating conditions is maintained.

    TI performs High Temperature Operating Life (HTOL) per JESD22-A108, which helps determine a device’s intrinsic reliability by simulating operation and aging over its’ lifetime. The qualification report shows x3 lots passed HTOL testing at 125C for 1000hrs, which is equivalent to approximately 9 years of use at 55C.
