Questions

Is there a KiCad symbol and footprint for the ISO7221AD?

Yes. The symbol is Analog & Interface:ISO7221A and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ISO7221AD?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the ISO7221AD datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the ISO7221AD?

JLCPCB lists it as part C28037, with 6,673 in stock; the sellers' links on this page open their listings.

What can replace the ISO7221AD?

Parts like it in the library: the ADUM1201ARZ-RL7 by Analog Devices, the CA-IS3720HS by Chipanalog, the CA-IS3721HS by Chipanalog and the ISO7721D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ISO7221AD?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
