Is there a KiCad symbol and footprint for the PCA9554APW?
Yes. 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 PCA9554APW?
TSSOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the PCA9554APW datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the PCA9554APW?
JLCPCB lists it as part C3194390, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PCA9554APW?
Parts like it in the library: the PCA9554PW by NXP Semiconductors, the PCA9557PW by NXP Semiconductors, the TCA9534PW by Texas Instruments and the TCA9534APW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
