ISO7763: Looking for a different Iso

Nate Newman

Part Number: ISO7763

Tool/software:

Hi team,

I'm making a reference design for an I/O module. Right now I have two ISO7763Ds sending SPI signals out to a high side switch and a stepper motor driver. I'd like to replace these with a single digital isolator that has 5 channels (4 SPI channels, 1 chip select). Do you have a part that would meet these requirements?

I've attached a block diagram, with the relevant socket outlined in red.

Hi Nate,

Thank you for your question.

I understand you would like to have a 5 channel digital isolator.

Currently, we do not offer a digital isolator that has 5 channels exactly.

However, our 6 channel digital isolator devices, such as the ISO676x and ISO776x, may be an option for you. There are several channel configurations that you can select in terms of the number of forward/reverse channels: https://www.ti.com/isolation/digital-isolators/products.html#480=6&
