Hello. My apologies if this has been answered before but unable to locate a proper definition to the various versions of this digital isolator. Very confused.
The following are available:
ISOW7741BDFMR
ISOW7741DFMR
ISOW7741FBDFMR
ISOW7741FDFMR
From the datasheet, if the suffix is:
ISOW7741DFMR ; reinforced?
ISOW7741FDFMR ; reinforced?
ISOW7741BDFMR ; basic?
ISOW7741FBDFMR ; basic?
The isolation field in the search table lists each of the above as BASIC isolation. Which is correct?
Thanks.
Hi,
Thank you for reaching out and sorry about various codes in part numbers.
Please check the below FAQ that explains what each character means in a part number, this is applicable to ISOW7741 as well.
As stated in the FAQ, the presence of 'F' immediately after the digits indicates a default output state of LOW while its absence indicates a default output state of HIGH. Similarly, as you correctly pointed out, the presence of 'B' indicates basic isolation while its absence indicates reinforced isolation. This is also shown in the below table from datasheet first page.
Let me know if you have any further questions, thanks.
Regards,
Koteshwar Rao
