Overview

The LM393ADT is a comparator made by STMicroelectronics in a SO-8 package with 8 pins. -18V~-1V、1V~18V 0℃~+70℃ 1.3us 100nA 2 2.5mA 2V~36V 2mV 36V 3nA Open-drain TTL、CMOS SO-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. 40,239 are in stock at JLCPCB (part C136033). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LM393ADT?

Yes. The symbol is Comparator:LM393 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM393ADT?

SO-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM393ADT datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the LM393ADT?

JLCPCB lists it as part C136033, with 40,239 in stock; the sellers' links on this page open their listings.

What can replace the LM393ADT?

Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM393ADT?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
