SN65HVD09: IBIS or Spice model

Part Number: SN65HVD09
Other Parts Discussed in Thread: SN75976A

Looking for a more recent IBIS model for the SN65HVD09.  There is an old IBIS ver 2.1 model circling the internet that I found, but it does not have rising/falling waveform data for the Bus I/O or TTL I/O Models.  I believe this causes and error when loading that file into ADS.  I've attached the file that is not working for me.

    Hi Lester,

    An engineer has been assigned to this thread and will respond to you shortly. Please allow some time for the Holiday season.

    Lester,

    Apologies for the delay during the holiday season.

    We don't have an IBIS model for the SN65HVD09, but we have one for the SN75976A, which should provide you with very similar behavior.

    Hi Danny, 

    The IBIS file available on the TI site for the SN75976A has identical content as the one I found on the web for the SN65HVD09.  It is still missing the rising/falling waveform data for the Bus I/O model and therefore triggers the same error message when I try to run it in ADS.  Are there any RS-485/RS-422 devices from the portfolio that have IBIS files with rising/falling waveform data where the data can be used to emulate the SN65HVD09 BUS I/O?

    Hi Lester,

    While we do have IBIS models with rising/falling data (many of our newer devices have rising/falling waveform data)  they don't accurately match the SN65HVD09 performance. And the ones we do have lean to the faster side of acceptable values. 

    Is there any specific questions that I could potentially help clear up on the device itself - I understand if not, but I don't think we have a model that will accurately predict what you are trying to design so I want to see if there is anything else that we can do to try to give a solution for as I don't think an IBIS model will made for this device due to the age of the device.

    Best,
