Is there a KiCad symbol and footprint for the TCA9535DB?
Yes. The symbol is Interface_Expansion:TCA9535DBR and the footprint Package_SO:SSOP-24_5.3x8.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TCA9535DB?
SSOP-24-208mil, with 24 pins. Its footprint is drawn on this page.
Where is the TCA9535DB datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TCA9535DB?
JLCPCB lists it as part C2652322, with 52 in stock; the sellers' links on this page open their listings.
What can replace the TCA9535DB?
Parts like it in the library: the TCA9555DB by Texas Instruments, the PCA9555DB by Texas Instruments, the MAX7312AAG+T by Maxim Integrated (Analog Devices) and the MAX7318AAG+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
