What package is the PCF8575DW?

SOIC-24-300mil, with 24 pins. Its footprint is drawn on this page.

Where is the PCF8575DW datasheet?

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

Where can I order the PCF8575DW?

JLCPCB lists it as part C2652278, with 655 in stock; the sellers' links on this page open their listings.

What can replace the PCF8575DW?

Parts like it in the library: the PCA9539DW by Texas Instruments, the PCA9555DW by Texas Instruments, the MAX7312AWG+ by Maxim Integrated (Analog Devices) and the PCA9535DW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
