LM339SR

COSINE · Comparators · SOP-14

LM339SR from COSINE, in a SOP-14. 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 OUT2 output Output of comparator 2, open-drain; connect to a load or pull-up resistor.
2 OUT1 output Output of comparator 1, open-drain; connect to a load or pull-up resistor.
3 +Vs power_in Positive power supply (2V to 36V single supply); place a 0.1µF bypass capacitor as close to the part as possible.
4 -IN1 input Inverting input of comparator 1; voltage range -Vs -0.3V to +Vs +0.3V.
5 +IN1 input Non-inverting input of comparator 1; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
6 -IN2 input Inverting input of comparator 2; voltage range -Vs -0.3V to +Vs +0.3V.
7 +IN2 input Non-inverting input of comparator 2; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
8 -IN3 input Inverting input of comparator 3; voltage range -Vs -0.3V to +Vs +0.3V.
9 +IN3 input Non-inverting input of comparator 3; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
10 -IN4 input Inverting input of comparator 4; voltage range -Vs -0.3V to +Vs +0.3V.
11 +IN4 input Non-inverting input of comparator 4; same voltage range as -IN (-Vs -0.3V to +Vs +0.3V).
12 -Vs power_in Negative power supply or ground; if not grounded, bypass with a 0.1µF capacitor close to the part.
13 OUT4 output Output of comparator 4, open-drain; connect to a load or pull-up resistor.
14 OUT3 output Output of comparator 3, open-drain; connect to a load or pull-up resistor.

CAD (KiCad official)

  • Symbol: LM339SR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14 (KiCad packages3D, STEP)
  • 3D model files: lm339sr-etched.step / lm339sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm339sr.step / lm339sr.glb are the bare package body.
