Questions
Is there a KiCad symbol and footprint for the PCA8550D?
Yes. The symbol is EasyEDA_Cloud:PCA8550D and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA8550D?
SO-16, with 16 pins. Its footprint is drawn on this page.
Where is the PCA8550D datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA8550D?
JLCPCB lists it as part C3207955, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PCA8550D?
Parts like it in the library: the 74HC138D by Nexperia, the EM74HC138D by EnergyMath, the CD4028BM(LX) by lingxingic and the CJ74HC157AEN by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
