Questions

Is there a KiCad symbol and footprint for the PCA9539DB?

Yes. The symbol is Analog & Interface:PCA9539DB and the footprint Package_SO:SSOP-24_5.3x8.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA9539DB?

SSOP-24-208mil, with 24 pins. Its footprint is drawn on this page.

Where is the PCA9539DB datasheet?

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

Where can I order the PCA9539DB?

JLCPCB lists it as part C2873268, with 11 in stock; the sellers' links on this page open their listings.

What can replace the PCA9539DB?

Parts like it in the library: the PCF8575DB by Texas Instruments, the PCF8575TS/1 by Nexperia, the PCA9555DB by NXP Semiconductors and the PCA9535DB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
