The LM393M is a comparator made by Texas Instruments in a SOIC-8 package with 8 pins. -18V~-1V、1V~18V 0℃~+70℃ 1.3us 2 25nA 2V~36V 2mV 300ns 36V 400uA 5nA Open Collector TTL、CMOS SOIC-8 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LM393, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 3,591 are in stock at JLCPCB (part C352858). 1 open-source board in 1 repository on GitHub use it.
