LM393ADR

Texas Instruments · Comparators · SOIC-8

LM393ADR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Output pin of comparator 1; open-drain NPN stage that sinks current to ground when negative input exceeds positive input by more than offset voltage, with maximum low-level voltage of 700mV at 4mA sink current over operating temperature range.
2 1IN- input Negative input pin of comparator 1; input voltage must remain within common-mode range of 0V to (VCC - 2V) over full operating temperature.
3 1IN+ input Positive input pin of comparator 1; input voltage must remain within common-mode range of 0V to (VCC - 2V) over full operating temperature.
4 GND power_in Ground; negative supply reference and signal return path for both comparators.
5 2IN+ input Positive input pin of comparator 2; input voltage must remain within common-mode range of 0V to (VCC - 2V) over full operating temperature.
6 2IN- input Negative input pin of comparator 2; input voltage must remain within common-mode range of 0V to (VCC - 2V) over full operating temperature.
7 2OUT output Output pin of comparator 2; open-drain NPN stage that sinks current to ground when negative input exceeds positive input by more than offset voltage, with maximum low-level voltage of 700mV at 4mA sink current over operating temperature range.
8 VCC power_in Positive supply voltage; device operates from 2V to 30V with quiescent current 0.60mA to 2.5mA depending on supply voltage and temperature.
