Part Number: ISO7241M
Other Parts Discussed in Thread: ISO7741

Hello Team,

My Customer would like to know if theISO7241M work at DC for an unlimited amount of time or does it require periodic switching? They intend to use this chip to isolate a steady-state enable signal for >24 hours

Thanks in Advance.

Regards,

-Renan

    Hi Renan,

    Thank you for posting to E2E! A periodic switching of signals is not necessary for our digital isolators, however we do recommend our newer ISO7741 for this application as it is a more robust device with increased isolation performance.
