ISO724 - How to isolate the MCU properly?

Kash Olia

Michael,
Since I have four signals that need to be isolated, what do you think about digital isolator "ISO724"? This is the one used to isolate JTAG from USB in the schematic of Launchpad-28069M?

Hi Kash,

I would recommend to go with our latest ISO774x family of digital isolators.
The ISO774x has superior reinforced isolation, is more robust to various kinds of EMC disturbances and are immune to CMTI events as high as 100kV/us.
