Overview

The ISO7842DW is a digital Isolator made by Texas Instruments in a SOIC-16-300mil package with 16 pins. -55℃~+125℃ 100Mbps 100kV/us 11ns 2 2 2.25V~5.5V 2.25V~5.5V 5700 High Level SOIC-16-300mil Digital Isolators ROHS.

PCBKit's library has its KiCad symbol (Analog & Interface:ISO7842, from CERN's library) and its footprint (Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2871218).

Questions

Is there a KiCad symbol and footprint for the ISO7842DW?

Yes. The symbol is Analog & Interface:ISO7842 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 ISO7842DW?

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

Where is the ISO7842DW datasheet?

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

Where can I order the ISO7842DW?

JLCPCB lists it as part C2871218, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ISO7842DW?

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.
