**Texas Instruments** · Temperature Sensors · VSSOP-8-0.65mm

LM75AIMM from Texas Instruments, in a VSSOP-8-0.65mm. 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 | SDA | bidirectional | I2C serial bi-directional data line, open-drain interface connected to controller with pull-up resistor or current source. |
| 2 | SCL | input | I2C clock input from controller, tied to pull-up resistor or current source. |
| 3 | O.S. | tri_state | Overtemperature shutdown open-drain output with pull-up resistor to controller interrupt line. |
| 4 | GND | power_in | Power supply ground. |
| 5 | A2 | input | User-set I2C address input; connect to ground for logic 0 or +VS for logic 1. |
| 6 | A1 | input | User-set I2C address input; connect to ground for logic 0 or +VS for logic 1. |
| 7 | A0 | input | User-set I2C address input; connect to ground for logic 0 or +VS for logic 1. |
| 8 | +VS | power_in | Positive supply voltage input, DC 2.7 V to 5.5 V, with 100-nF bypass and 10-µF bulk capacitance nearby. |

## CAD (KiCad official)

- Symbol: `LM75AIMM`
- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`
- 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)
- 3D model files: `lm75aimm-etched.step` / `lm75aimm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm75aimm.step` / `lm75aimm.glb` are the bare package body.
