Questions
Is there a KiCad symbol and footprint for the PCA9555DB?
Yes. The symbol is Interface_Expansion:PCA9555DB and the footprint Package_SO:SSOP-24_5.3x8.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9555DB?
SSOP-24-208mil, with 24 pins. Its footprint is drawn on this page.
Where is the PCA9555DB datasheet?
NXP Semiconductors publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9555DB?
JLCPCB lists it as part C133183, with 83 in stock; the sellers' links on this page open their listings.
What can replace the PCA9555DB?
Parts like it in the library: the PCF8575DB by Texas Instruments, the PCF8575TS/1 by Nexperia, the PCA9539DB by Texas Instruments and the PCA9535DB by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
