Questions
Is there a KiCad symbol and footprint for the ISO7021D?
Yes. The symbol is EasyEDA_Cloud:XLISO7221CDR 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 ISO7021D?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the ISO7021D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the ISO7021D?
JLCPCB lists it as part C2867957, with 326 in stock; the sellers' links on this page open their listings.
What can replace the ISO7021D?
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.
