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 | Serial data pin for the SMBus/I²C interface. Open-drain output; requires an external pull-up resistor to V+. |+| 2 | SCL | input | Serial clock input pin for the SMBus/I²C interface. Open-drain; requires an external pull-up resistor to V+. Supports up to 400 kHz fast mode and 2.75 MHz high-speed mode. |+| 3 | ALERT | output | Overtemperature alarm output. Open-drain; requires an external pull-up resistor. Configurable polarity (POL bit) and comparator/interrupt behavior (TM bit). |+| 4 | GND | power_in | Ground reference pin. |+| 5 | A2 | input | Slave address select pin bit 2. Tie to V+ or GND to select one of eight I²C slave addresses (1001xxx). |+| 6 | A1 | input | Slave address select pin bit 1. Tie to V+ or GND to select one of eight I²C slave addresses (1001xxx). |+| 7 | A0 | input | Slave address select pin bit 0. Tie to V+ or GND to select one of eight I²C slave addresses (1001xxx). |+| 8 | V+ | power_in | Positive supply voltage input. Operating range 1.4 V to 5.5 V (recommended 3.0 V to 5.5 V). Bypass locally with a 0.1 µF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ADT75ARZ-REEL-TUDI`+- `ADT75ARMZ-REEL-TUDI`+- `ADT75BRMZ-REEL-TUDI`++## CAD (KiCad official)++- Symbol: `ADT75ARZ-REEL-TUDI`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Tudi datasheet](docs/adt75arz-reel-tudi-datasheet.pdf) (15 pp, sha256 `741b5191d35ac0d5`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
