The symbol is EasyEDA_Cloud:TLC274MDRG4 and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
SOIC-14, with 14 pins. Its footprint is drawn on this page.
Texas Instruments publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C2873155, with 0 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the LM324D by onsemi, the LM2902DT by STMicroelectronics, the LM324DT by STMicroelectronics and the LMV324ID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
