Is there a KiCad symbol and footprint for the SN54LS251J?
Yes. The symbol is EasyEDA_Cloud:SN74AS151NS and the footprint EasyEDA_Cloud:PDIP-16_L19.7-W6.6-P2.54-LS7.6-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SN54LS251J?
CDIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the SN54LS251J datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN54LS251J?
JLCPCB lists it as part C3208708, with 3 in stock; the sellers' links on this page open their listings.
What can replace the SN54LS251J?
Parts like it in the library: the SN54ALS138AJ by Texas Instruments, the IDT74FCT257TP by Renesas Electronics, the IH5048CJE by Maxim Integrated (Analog Devices) and the IH5140CJE by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
