Questions

Is there a KiCad symbol and footprint for the SIT3485ESA?

Yes. The symbol is EasyEDA_Cloud:SN75176ADR-MS and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SIT3485ESA?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the SIT3485ESA datasheet?

SIT publishes it: the Datasheet link on this page opens it.

Where can I order the SIT3485ESA?

JLCPCB lists it as part C313015, with 254 in stock; the sellers' links on this page open their listings.

What can replace the SIT3485ESA?

Parts like it in the library: the GM3085E by GATEMODE, the SP3485EEN by UMW, the BL3085(I47) by BL and the SSP485 by Shanghai Siproin Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SIT3485ESA?
