Is there a KiCad symbol and footprint for the ISO6740DW?
Yes. The symbol is Isolator:ISO6740 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 ISO6740DW?
SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.
Where is the ISO6740DW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the ISO6740DW?
JLCPCB lists it as part C5216421, with 1,128 in stock; the sellers' links on this page open their listings.
What can replace the ISO6740DW?
Parts like it in the library: the ISO7741DW by Texas Instruments, the SSP5840ED by Shanghai Siproin Microelectronics, the ISO7740DW by Texas Instruments and the ISO7760FDWR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
