Is there a KiCad symbol and footprint for the HCPL0637?
Yes. The symbol is EasyEDA_Cloud:HCPL062NR1 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 HCPL0637?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the HCPL0637 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the HCPL0637?
JLCPCB lists it as part C891329, with 304 in stock; the sellers' links on this page open their listings.
What can replace the HCPL0637?
