Questions
Is there a KiCad symbol and footprint for the PCA9538BS?
Yes. The symbol is Interface_Expansion:PCA9538BS and the footprint Package_DFN_QFN:NXP_VQFN-16-1EP_4x4mm_P0.65mm_EP2.1x2.1mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the PCA9538BS?
HVQFN-16-EP(4x4), with 17 pins. Its footprint is drawn on this page.
Where can I order the PCA9538BS?
JLCPCB lists it as part C2652342, with 0 in stock; the sellers' links on this page open their listings.
What can replace the PCA9538BS?
Parts like it in the library: the PCA9555PW by NXP Semiconductors, the AW9523BTQR by AWINIC, the TCA6416ARTWR by Texas Instruments and the TCA9535PW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
