Yes. The symbol is EasyEDA_Cloud:SN75176ADR-MS 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.
SO-8, with 8 pins. Its footprint is drawn on this page.
STMicroelectronics publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C1509141, with 3,033 in stock; the sellers' links on this page open their listings.
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.
