# TMP75AIDRG4

**Texas Instruments** · Temperature Sensors · SOIC-8

TMP75AIDRG4 from Texas Instruments, in a SOIC-8. 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 | Serial data. Open-drain output; requires a pullup resistor. |
| 2 | SCL | input | Serial clock. Open-drain output; requires a pullup resistor. |
| 3 | ALERT | output | Overtemperature alert. Open-drain output; requires a pullup resistor. |
| 4 | GND | power_in | Ground. |
| 5 | A2 | input | Address select. Connect to GND, V+ or (for the TMP175 device only) leave these pins floating. |
| 6 | A1 | input | Address select. Connect to GND, V+ or (for the TMP175 device only) leave these pins floating. |
| 7 | A0 | input | Address select. Connect to GND, V+ or (for the TMP175 device only) leave these pins floating. |
| 8 | V+ | power_in | Supply voltage, 2.7 V to 5.5 V. |

## CAD (KiCad official)

- Symbol: `TMP75AIDRG4`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tmp75aidrg4-etched.step` / `tmp75aidrg4-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp75aidrg4.step` / `tmp75aidrg4.glb` are the bare package body.
