Overview
The SN74LS685N is a comparator made by Texas Instruments in a DIP-20 package with 20 pins. Built-in hysteresis DIP-20 Comparators.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SN74LS685N, from EasyEDA) and its footprint (Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3659142).
