TCAL9539-Q1: Use as MSDI

Part Number: TCAL9539-Q1
Other Parts Discussed in Thread: TIC10024-Q1,

Hi team,

Can this use as a replacement for TIC10024-Q1? I'd like to check if this device can be used as 16ch MSDI.

Best Regards,


  • The TCAL9539-Q1 has plain logic inputs. The TIC10024-Q1's inputs are much more robust and flexible, so it is unlikely that the TCAL would be able to handle the input signals in your application.

  • Hi Shoji,

    The TIC10024-Q1 is designed for higher voltage automotive applications. TCAL9539-Q1 inputs are not rated for 12V unlike the TIC10024 where it can range from -24V to 40V abs. max (TCAL9539-Q1 is rated up to 4V I believe). 

    I don't know the customer application entirely, but I would err on the side that TCAL9539-Q1 probably wouldn't work in replacement of the TIC10024. Do we have more information on the system specs of the customer design? What is the customer attempting to accomplish here? 



  • Hi Ladisch,

    Thank you for your quick answer.

    Best Regards,
