Questions
Is there a KiCad symbol and footprint for the SN74ALS21ANS?
Yes. The symbol is EasyEDA_Cloud:SN74LS21N(XBLW) and the footprint EasyEDA_Cloud:SO-14_L10.2-W5.3-P1.27-LS7.8-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN74ALS21ANS?
SO-14-208mil, with 14 pins. Its footprint is drawn on this page.
Where is the SN74ALS21ANS datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74ALS21ANS?
JLCPCB lists it as part C2878796, with 1 in stock; the sellers' links on this page open their listings.
What can replace the SN74ALS21ANS?
Parts like it in the library: the CD4012BNSR by Texas Instruments, the SN74HC266NS by Texas Instruments, the SN74LS21NSR by Texas Instruments and the CD4072BNSR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
