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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8-0.65mm |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `LM75BIMMX-3IMM`+- `LM75BIMMX-3IMMX`+- `LM75BIMMX-3IM`+- `LM75BIMMX-3IMX`++## CAD (KiCad official)++- Symbol: `LM75BIMMX-3`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/lm75bimmx-3-datasheet.pdf) (34 pp, sha256 `0521fbcb47540981`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
