ISO1541: IBIS model question related to VOL

Part Number: ISO1541

Hello expert,

My customer would like to know IBIS model behavior of ISO1541. 

They used below IBIS model to simulate I2C signal , but they cannot see 0.65V~0.8V on side 1. Based on datasheet, there should be 0.65V~0.8V on side 1. Is there anything missing? Thanks!

Best regards,

    Hello Ann Lien, 

    Thank you for reaching out. It looks like this is the correct waveform based on the values loaded in the IBIS model. Actual device behavior will be as shown in the datasheet. 

    I will confirm this with the team and get back to you, however, this will take some time. I will go ahead and close this post. Let me know if you have further questions. 

    Best,
    Andrew
