LM75BIMMX-3

Texas Instruments · Temperature and Humidity Sensor · VSSOP-8-0.65mm

LM75BIMMX-3 from Texas Instruments, in a VSSOP-8-0.65mm. 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 pullup resistor or current source to +VS. VIH = +VS × 0.7 min, VIL = +VS × 0.3 max. Absolute-max voltage 6.5 V.
2 SCL input I2C serial clock input. Requires an external pullup resistor to +VS. Supports operation up to 400 kHz. Absolute-max voltage 6.5 V.
3 O.S. output Over-temperature shutdown output. Open-drain; requires a pullup resistor to the controller interrupt line. Active-low when the measured temperature exceeds the programmed T_OS limit (default 80°C, T_HYST 75°C). O.S. output saturation voltage 0.8 V max at 4 mA sink; max sink current 10 mA.
4 GND power_in Power supply ground reference for the device.
5 A2 input User-set I2C address input (MSB of the 3-bit address selector). Tie to GND (logic 0) or +VS (logic 1). Absolute-max voltage (+VS + 0.3) V and must be ≤ 6.5 V.
6 A1 input User-set I2C address input. Tie to GND (logic 0) or +VS (logic 1). Absolute-max voltage (+VS + 0.3) V and must be ≤ 6.5 V.
7 A0 input User-set I2C address input (LSB of the 3-bit address selector). Tie to GND (logic 0) or +VS (logic 1). Absolute-max voltage (+VS + 0.3) V and must be ≤ 6.5 V.
8 +VS power_in Positive supply voltage input. DC 3 V to 5.5 V (LM75BIMMX-3 nominal 3.3 V). Decouple with a 100-nF bypass capacitor close to the pin plus 10-µF bulk capacitance in the near vicinity. Operating supply current 280 µA typical; shutdown 4 µA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm75bimmx-3.step 122 KB You want the bare part, or you mark your own boards.
lm75bimmx-3-etched.step 1.8 MB You want the part with LM75BIMMX-3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 478 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 (34 pp, sha256 0521fbcb47540981, retrieved 2026-08-17, tier: lcsc)
  • 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).
