Overview
The ST1480ACDR is a RS 485 , RS 422 IC made by STMicroelectronics in a SOIC-8 package with 8 pins. 0℃~+70℃ 1 1 1.3mA 15Mbps 3V~3.6V 64 Half-Duplex Transceiver ±15kV SOIC-8 RS-485 / RS-422 ICs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:MS2111, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 679 are in stock at JLCPCB (part C155607). 2 open-source boards in 2 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the ST1480ACDR?
Yes. The symbol is EasyEDA_Cloud:MS2111 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST1480ACDR?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the ST1480ACDR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ST1480ACDR?
JLCPCB lists it as part C155607, with 679 in stock; the sellers' links on this page open their listings.
What can replace the ST1480ACDR?
Parts like it in the library: the SP3485EN-L/TR by MaxLinear, the SP485EEN-L/TR by MaxLinear, the SN75176BD by Texas Instruments and the MAX485ESA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ST1480ACDR?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
