Questions

Is there a KiCad symbol and footprint for the PCA9557PW?

Yes. The symbol is Interface_Expansion:PCA9557PW 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 PCA9557PW?

TSSOP-16, with 16 pins. Its footprint is drawn on this page.

Where is the PCA9557PW datasheet?

NXP Semiconductors publishes it: the Datasheet link on this page opens it.

Where can I order the PCA9557PW?

JLCPCB lists it as part C141380, with 6,985 in stock; the sellers' links on this page open their listings.

What can replace the PCA9557PW?

Parts like it in the library: the PCA9554PW by NXP Semiconductors, the TCA9534PW by Texas Instruments, the TCA9534APW by Texas Instruments and the TCA9554PW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the PCA9557PW?

18 boards in 15 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
