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/SMBus serial data. Open-drain bidirectional line; requires an external pullup resistor (typ. 5 kΩ) to V+. VOL = 0.15 V typ at IOL = 3 mA. |+| 2 | SCL | input | I2C/SMBus serial clock input. Open-drain; requires an external pullup resistor to V+. Supports Fast (400 kHz) and High-Speed (up to 2.38 MHz) modes. |+| 3 | ALERT | output | Overtemperature alert output. Open-drain; requires an external pullup resistor. VOL = 0.15 V typ at IOL = 4 mA. Asserts when the measured temperature exceeds the programmed limit per the SMBus alert function. |+| 4 | GND | power_in | Device ground return. |+| 5 | A2 | input | I2C address select bit 2. Connect to GND or V+ to set one of the eight possible slave addresses. |+| 6 | A1 | input | I2C address select bit 1. Connect to GND or V+ to set one of the eight possible slave addresses. |+| 7 | A0 | input | I2C address select bit 0. Connect to GND or V+ to set one of the eight possible slave addresses. |+| 8 | V+ | power_in | Positive supply, 2.7 V to 5.5 V (7 V absolute max). Bypass with a 0.01 µF (or larger) ceramic capacitor to GND close to the pin. Typical IQ = 50 µA (bus inactive). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `TMP275AIDRAIDR`+- `TMP275AIDRAID`+- `TMP275AIDRAIDGKR`+- `TMP275AIDRAIDGKT`++## CAD (KiCad official)++- Symbol: `TMP275AIDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmp275a.pdf) (34 pp, sha256 `dc06223f8413fc81`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
