Questions

Is there a KiCad symbol and footprint for the OC7140?

Yes. The symbol is EasyEDA_Cloud:OC7140 and the footprint EasyEDA_Cloud:ESOP-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the OC7140?

SOIC-8-EP, with 9 pins. Its footprint is drawn on this page.

Where is the OC7140 datasheet?

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

Where can I order the OC7140?

JLCPCB lists it as part C842736, with 6,480 in stock; the sellers' links on this page open their listings.

What can replace the OC7140?

Parts like it in the library: the PT4123EESH by PowTech, the OC6700B by OCX, the MT7223 by MAXIC Tech and the RM9005E by Reactor-Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
