Questions

Is there a KiCad symbol and footprint for the ISO1050DW?

Yes. The symbol is EasyEDA_Cloud:PAI8451-W1R and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ISO1050DW?

SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.

Where is the ISO1050DW datasheet?

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

Where can I order the ISO1050DW?

JLCPCB lists it as part C93718, with 9,244 in stock; the sellers' links on this page open their listings.

What can replace the ISO1050DW?

Parts like it in the library: the CA-IS3050W by Chipanalog, the CA-IS3052W by Chipanalog, the ADM3054BRWZ-RL7 by Analog Devices and the ADM3052BRWZ-REEL7 by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ISO1050DW?

10 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
