LM75AIMX

Texas Instruments · Temperature and Humidity Sensor · SOIC-8

LM75AIMX 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 SDA bidirectional I2C serial bi-directional data line, open-drain. Requires an external pull-up resistor or current source to +Vs. Operates up to 400 kHz.
2 SCL input I2C serial clock input. Driven by the bus controller; requires external pull-up to +Vs. Operates up to 400 kHz.
3 O.S. output Overtemperature Shutdown output, open-drain. Requires an external pull-up resistor; drives a controller interrupt line. Programmable T_OS/T_HYST limits with user-configurable fault-tolerance (up to 6 consecutive over-limit conversions). I_OL up to 4 mA (V_OL max 0.8 V).
4 GND power_in Power supply ground reference for the device.
5 A2 input User-set I2C address input bit 2. Tie to GND for logic '0' or to +Vs for logic '1'. Combined with A1/A0, allows up to eight LM75A devices on the same bus.
6 A1 input User-set I2C address input bit 1. Tie to GND for logic '0' or to +Vs for logic '1'.
7 A0 input User-set I2C address input bit 0. Tie to GND for logic '0' or to +Vs for logic '1'.
8 +VS power_in Positive supply voltage input, 2.7 V to 5.5 V. Bypass with a 100 nF ceramic capacitor close to the pin and a 10 µF bulk capacitor in the near vicinity. Typical operating current 280 µA; 4 µA in shutdown mode.

CAD (KiCad official)

  • Symbol: LM75AIMX
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm75aimx-etched.step / lm75aimx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm75aimx.step / lm75aimx.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm75aimx.step 122 KB You want the bare part, or you mark your own boards.
lm75aimx-etched.step 1.3 MB You want the part with LM75AIMX already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 348 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (30 pp, sha256 004750df9cb9c1b1, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
