Overview
The 74ACT299PC is a shift Register made by onsemi in a PDIP-20 package with 20 pins. -40℃~+85℃ 1 4.5V~5.5V 74ACT Tri-State PDIP-20 Shift Registers ROHS.
PCBKit's library has its KiCad symbol (74xx:74LS299, from KiCad's library) and its footprint (Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3304031).

Is there a KiCad symbol and footprint for the 74ACT299PC?
Yes. The symbol is 74xx:74LS299 and the footprint Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 74ACT299PC?
PDIP-20, with 20 pins. Its footprint is drawn on this page.
Where is the 74ACT299PC datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the 74ACT299PC?
JLCPCB lists it as part C3304031, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 74ACT299PC?
Parts like it in the library: the AM25LS22PC by AMD, the 74ACT323PC by onsemi, the 74F299PC by onsemi and the 74F322PC by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
