Is there a KiCad symbol and footprint for the PCF8574DWR?
Yes. The symbol is EasyEDA_Cloud:TCA9554DBR 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 PCF8574DWR?
SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.
Where is the PCF8574DWR datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCF8574DWR?
JLCPCB lists it as part C2652271, with 3,840 in stock; the sellers' links on this page open their listings.
What can replace the PCF8574DWR?
Parts like it in the library: the PCF8574T/3,518 by NXP Semiconductors, the PCF8574T/TR by HGSEMI, the PCF8574AT/TR by HGSEMI and the PCF8574ADWR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
