# TMP107BIDR

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

TMP107BIDR 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 | V+ | power_in | Supply voltage, 1.7 V to 5.5 V |
| 2 | R1 | input | Built-in pullup resistor for ALERT1; float or connect to V+ |
| 3 | I/O1 | bidirectional | SMAART wire input, output 1 |
| 4 | ALERT1 | output | Over- and undertemperature alert. Open-drain output; internally connected to pullup resistor R1. |
| 5 | GND | power_in | Ground |
| 6 | ALERT2 | output | Over- and undertemperature alert. Open-drain output; internally connected to pullup resistor R2. |
| 7 | I/O2 | bidirectional | SMAART wire input, output 2 |
| 8 | R2 | input | Built-in pullup resistor for ALERT2; float or connect to V+ |

## CAD (KiCad official)

- Symbol: `TMP107BIDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tmp107bidr-etched.step` / `tmp107bidr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp107bidr.step` / `tmp107bidr.glb` are the bare package body.
