Is there a KiCad symbol and footprint for the PCA9535DW?
Yes. The symbol is EasyEDA_Cloud:TCA9535PWR(UMW) and the footprint Package_SO:SOIC-24W_7.5x15.4mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9535DW?
SOIC-24-300mil, with 24 pins. Its footprint is drawn on this page.
Where is the PCA9535DW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9535DW?
JLCPCB lists it as part C2652297, with 20 in stock; the sellers' links on this page open their listings.
What can replace the PCA9535DW?
Parts like it in the library: the PCF8575DW by Texas Instruments, the PCA9539DW by Texas Instruments, the PCA9555DW by Texas Instruments and the MAX7312AWG+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
