Is there a KiCad symbol and footprint for the PCA9535RTW?
Yes. The symbol is EasyEDA_Cloud:TCA9555RTWR(UMW) and the footprint EasyEDA_Cloud:HWQFN-24_L4.0-W4.0-P0.50-TL-EP2.5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9535RTW?
WQFN-24(4x4), with 25 pins. Its footprint is drawn on this page.
Where is the PCA9535RTW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9535RTW?
JLCPCB lists it as part C3188832, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PCA9535RTW?
Parts like it in the library: the PCA9535AHF,128 by NXP Semiconductors, the PCA6416AHF by NXP Semiconductors, the TCA6416RTW by Texas Instruments and the NCA9555BY-Q100HP by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
