LM393SR

COSINE · Comparators · SOP-8

LM393SR from COSINE, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of comparator 1, open-drain; connect to a load or pull-up resistor.
2 -IN1 input Inverting input of comparator 1; voltage range from -Vs -0.3V to +Vs +0.3V.
3 +IN1 input Non-inverting input of comparator 1; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
4 -Vs power_in Negative power supply or ground; if not connected to ground, bypass with a 0.1μF capacitor placed as close as possible.
5 +IN2 input Non-inverting input of comparator 2; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
6 -IN2 input Inverting input of comparator 2; voltage range from -Vs -0.3V to +Vs +0.3V.
7 OUT2 output Output of comparator 2, open-drain; connect to a load or pull-up resistor.
8 +Vs power_in Positive power supply, 2V to 36V single supply; place a 0.1μF bypass capacitor as close to the part as possible.

CAD (KiCad official)

  • Symbol: LM393SR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm393sr-etched.step / lm393sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm393sr.step / lm393sr.glb are the bare package body.
