Is there a KiCad symbol and footprint for the SN74ALS157ANS?
Yes. The symbol is 74xx:74LS157 and the footprint EasyEDA_Cloud:SOIC-16_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 SN74ALS157ANS?
SOIC-16-208mil, with 16 pins. Its footprint is drawn on this page.
Where is the SN74ALS157ANS datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the SN74ALS157ANS?
JLCPCB lists it as part C2674591, with 8 in stock; the sellers' links on this page open their listings.
What can replace the SN74ALS157ANS?
Parts like it in the library: the SN74AHC138NSR by Texas Instruments, the SN74LS145NSR by Texas Instruments, the SN74LS155ANS by Texas Instruments and the SN74LV157ANS by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
