Questions
Is there a KiCad symbol and footprint for the SN54LS673J?
Yes. The symbol is EasyEDA_Cloud:SN54LS673J, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN54LS673J?
CDIP-24, with 24 pins.
Where is the SN54LS673J datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN54LS673J?
JLCPCB lists it as part C3301258, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SN54LS673J?
Parts like it in the library: the HEF4021BT-Q100J by Nexperia, the SN74LS299N by Texas Instruments, the SN74LS674DW by Texas Instruments and the DM9328N by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
