Overview
The CD74AC299M is a shift Register made by Texas Instruments in a SOP-20 package with 20 pins. -55℃~+125℃ 1.5V~5.5V 108MHz 24mA 24mA 24mA 400mW 6ns@5V,50pF 74AC 8 Asynchronous clear function、Output enable、Supports forward and reverse shift Tri-State SOP-20 Shift Registers ROHS.
PCBKit's library has its KiCad symbol (74xx:74LS299, from KiCad's library) and its footprint (Package_SO:SOP-20_7.5x12.8mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3301231).

Questions
Is there a KiCad symbol and footprint for the CD74AC299M?
Yes. The symbol is 74xx:74LS299 and the footprint Package_SO:SOP-20_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CD74AC299M?
SOP-20, with 20 pins. Its footprint is drawn on this page.
Where is the CD74AC299M datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the CD74AC299M?
JLCPCB lists it as part C3301231, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CD74AC299M?
Parts like it in the library: the 74HC573D by Slkor, the SN74HC374DTR(XBLW) by XBLW, the NPIC6C4894D-Q100518 by Nexperia and the 74AC299SJ by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
