Questions
Is there a KiCad symbol and footprint for the PCA9556PW?
Yes. The symbol is EasyEDA_Cloud:PCA9556PW,118 and the footprint Package_SO:TSSOP-16_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9556PW?
TSSOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the PCA9556PW datasheet?
NXP Semiconductors publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9556PW?
JLCPCB lists it as part C7256525, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PCA9556PW?
Parts like it in the library: the PCF8574MT/TR by HGSEMI, the PCF8574T/3,518 by NXP Semiconductors, the PCF8574APWR by Texas Instruments and the PCF8574T/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
