PSPICE-FOR-TI: PSPICE-FOR-TI

Part Number: PSPICE-FOR-TI
Other Parts Discussed in Thread: ISO7242C, , ISO7742

Tool/software:

I am using ISO1042QDWRQ1 for CAN, ISO3086DWR for RS422, ISO7242CDWR for isolating RS232. Is there a way to simulate these interfaces and transceivers on TINA TI? Or any other softwares?

    Hi Joseph,

    Digital isolators and pseudo-differential drivers (like RS485, RS422/RS232 and CAN) are modeled using IBIS to evaulated signal integrity.

    Functinoally, digital isolators work like level shifters with a fixed delay.

    Since IBIS is a drive strength/edge  (or receiver loading impedence) event only, duty cycle and prop delay are not modeled. As a result, they can't be imported into TINA or PSpice.

    I can re-direct this to the product line for further support.

    Hi Joseph,

    As David stated, the IBIS models are more appropriate models for evaluating signal integrity and we have IBIS models available for most of our products2

    For digital isolators, I recommend you to consider ISO7742 which offers much better performance over ISO7242C. We do also have PSpice model for ISO7742 on its product page which you can simulate in PSPICE-FOR-TI. Let me know, thanks.
