SN74HC139: IBIS model

Part Number: SN74HC139
Other Parts Discussed in Thread: TINA-TI

Hi all

Would you mind if we ask SN74HC139?
Do you have SN74HC139NSR's IBIS model?
If you have it, could you give us?

Kind regards,

Hirotaka Matsumoto

  • Hello Matsumoto-san,
    Currently the only model available for the SN74HC139 is built into TINA-TI, and that model is functional only - it does not realistically represent the capabilities of the SN74HC139.

    Is there a specific application that you are trying to design this part into?
  • Emrys san

    Thank you for your reply!
    Our customer's application is Interphone.

    So, is it possible to make SN74HC139's model?
    If it is difficult, we will persuade that there is no IBIS model. 

    Kind regards,

    Hirotaka Matsumoto

  • Hi Matsumoto-san,
    I can request a model be created for the SN74HC139, however I do not know how long it would take. I know that the modelling team has a long backlog of devices currently, so having a large business case would help accelerate the process. Can you tell me about the project timeline and number of units/years requested? You can email me directly if you don't want this information shared publicly.

    Thank you for your cooperation!

    We will send  project timeline and number of units/years requested directly.
    Could you let us know your E-mail address? Or, is it possible to send using private message on E2E?
    My E-mail address : matsumoto-h@clv.macnica.co.jp

    And then, if you have IBIS model wihch is similar to SN74HC139, could you give us?

    Kind regards,

    Hirotaka Matsumoto

  • Matsumoto-san,
