Hi User6125253, all,

This crosstalk issue was resolved, but TI recommends using a digital isolator like the ISO77xx or ISO78xx family of devices for robust isolation performance over optocouplers. For assistance including a TI digital isolator in your project, please feel free to click the red or yellow buttons on the top right corner of this window.

Thank you,
