Overview
The ISO1644DW is an I2C Isolator made by Texas Instruments in a SOIC-16 package with 16 pins. -40℃~+125℃ 1.7MHz 100kV/us 5000 Bidirectional Open-drain buffer output、Hotswap SOIC-16 I2C Isolators ROHS.
PCBKit's library has its KiCad symbol (Isolator:ISO1644DWR, from KiCad's library) and its footprint (Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 867 are in stock at JLCPCB (part C5216232).

Questions
Is there a KiCad symbol and footprint for the ISO1644DW?
Yes. The symbol is Isolator:ISO1644DWR 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 ISO1644DW?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the ISO1644DW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the ISO1644DW?
JLCPCB lists it as part C5216232, with 867 in stock; the sellers' links on this page open their listings.
What can replace the ISO1644DW?
Parts like it in the library: the ISO1642DW 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.
