Is there a KiCad symbol and footprint for the SN74ALS299N?
Yes. The symbol is 74xx:74LS299 and the footprint Package_DIP:DIP-20_W7.62mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74ALS299N?
PDIP-20, with 20 pins. Its footprint is drawn on this page.
Where is the SN74ALS299N datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74ALS299N?
JLCPCB lists it as part C2872078, with 10 in stock; the sellers' links on this page open their listings.
What can replace the SN74ALS299N?
Parts like it in the library: the SN74HC374N(XBLW) by XBLW, the TPIC6B595N by Texas Instruments, the CD74HCT299E by Texas Instruments and the SN74LS299N by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
