Questions
Is there a KiCad symbol and footprint for the PCA9545APW?
Yes. The symbol is EasyEDA_Cloud:PCA9545APWT and the footprint Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9545APW?
TSSOP-20, with 20 pins. Its footprint is drawn on this page.
Where is the PCA9545APW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9545APW?
JLCPCB lists it as part C2149504, with 190 in stock; the sellers' links on this page open their listings.
What can replace the PCA9545APW?
Parts like it in the library: the PCA9544APW by NXP Semiconductors, the NCA9545-DTSR by NOVOSENSE, the PCA9545APW by NXP Semiconductors and the PCA9544APW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
