Questions
Is there a KiCad symbol and footprint for the PCA9555PW?
Yes. The symbol is Interface_Expansion:PCA9555PW and the footprint Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9555PW?
TSSOP-24, with 24 pins. Its footprint is drawn on this page.
Where is the PCA9555PW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9555PW?
JLCPCB lists it as part C2864778, with 7,144 in stock; the sellers' links on this page open their listings.
What can replace the PCA9555PW?
Parts like it in the library: the PCF8575PWRE4 by Texas Instruments, the TCA9555DB by Texas Instruments, the PCA9534DBR by Texas Instruments and the PCA9555DB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
