Is there a KiCad symbol and footprint for the MAX485ESA?
Yes. The symbol is Interface_UART:MAX485E 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 MAX485ESA?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the MAX485ESA datasheet?
IDCHIP publishes it: the Datasheet link on this page opens it.
Where can I order the MAX485ESA?
JLCPCB lists it as part C42436900, with 11,519 in stock; the sellers' links on this page open their listings.
What can replace the MAX485ESA?
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.
