Questions

Is there a KiCad symbol and footprint for the ISO1642DW?

Yes. The symbol is Isolator:ISO1642DWR and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ISO1642DW?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the ISO1642DW datasheet?

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

Where can I order the ISO1642DW?

JLCPCB lists it as part C5216228, with 362 in stock; the sellers' links on this page open their listings.

What can replace the ISO1642DW?

Parts like it in the library: the ISO1644DW by Texas Instruments, the SI8602AD-B-IS by Skyworks Solutions, the ISO1643DW by Texas Instruments and the MAX14933AWE+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ISO1642DW?

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