Is there a KiCad symbol and footprint for the CD74ACT20E?
Yes. The symbol is EasyEDA_Cloud:SN74LS21N(XBLW) and the footprint Package_DIP:DIP-14_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 CD74ACT20E?
PDIP-14, with 14 pins. Its footprint is drawn on this page.
Where is the CD74ACT20E datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the CD74ACT20E?
JLCPCB lists it as part C2859552, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CD74ACT20E?
Parts like it in the library: the CD4093BE by Texas Instruments, the CD4078BE by HGSEMI, the CD4093BE(XBLW) by XBLW and the CD4030BE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
