Part Number: ISO7721
Other Parts Discussed in Thread: ISOW7721, ISOW7821

Hi TIer

 

I see ISOW7721 is not pin2pin for ISO7721.

Do we have pin2pin chip can replace ISO7721 and include power ?

Thank you very much.

    Hi Tony,

    Thanks for reaching out. 

    The digital isolator with integrated DC/DC devices all have different pinout compared to a regular digital isolator. 

    I understand that customer is looking for a digital isolator with integrated DC/DC that has the same package and pin size as the ISO7721. I would like to recommend our ISOW6441 device, which is our newest generation isolation device. This device has the same package size and pin size as the ISO7721.

    The ISOW7821 is a digital isolator with integrated DC/DC that has the same package size and pin size as the ISO7721. The ISOW7721 has better EMC performance than the ISOW7821, but has different package option than ISO7721.
