Is there a KiCad symbol and footprint for the 74LS157PC?
Yes. The symbol is 74xx:74LS157 and the footprint Package_DIP:DIP-16_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 74LS157PC?
PDIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the 74LS157PC datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the 74LS157PC?
JLCPCB lists it as part C3210036, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 74LS157PC?
Parts like it in the library: the SN74HC138NED-GMIC by GREENMICRO, the 74HC138N by HGSEMI, the 74HC139N by HGSEMI and the 74HC238N by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
