@@ -0,0 +1,53 @@+# TMP75++**Texas Instruments** · Digital temperature sensor · SOIC-8++Digital temperature sensor with an I2C / SMBus interface in the industry-standard LM75 form factor and pinout, in a SOIC-8 package. A 12-bit ADC gives 0.0625 °C resolution with ±1 °C typical accuracy, and a programmable ALERT output flags over-temperature. Three address pins (A0-A2) allow up to eight sensors on one bus. The default board-temperature monitor; no external components beyond a bypass cap.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | SDA | bidirectional | Serial data line for the I2C/SMBus/Two-Wire interface. Open-drain output; requires an external pull-up resistor (typ. 4.7 kΩ). VIH ≥ 0.7·V+, VIL ≤ 0.3·V+; VOL ≤ 0.4 V at IOL = 3 mA. |+| 2 | SCL | input | Serial clock line for the I2C/SMBus/Two-Wire interface. Open-drain; requires an external pull-up resistor (typ. 4.7 kΩ). Supports standard, fast, and high-speed modes up to 3.4 MHz. |+| 3 | ALERT | output | Overtemperature alert / SMBus Alert output. Open-drain; requires an external pull-up resistor. VOL ≤ 0.4 V at IOL = 4 mA. Asserted when the measured temperature crosses the programmed THIGH/TLOW thresholds per the configuration register. |+| 4 | GND | power_in | Device ground reference (0 V). |+| 5 | A2 | input | I2C slave-address select bit 2. Tie to GND or V+ to set the corresponding address bit. May be left floating on the TMP75 for a third state, giving up to 8 selectable addresses. |+| 6 | A1 | input | I2C slave-address select bit 1. Tie to GND or V+ to set the corresponding address bit. May be left floating on the TMP75 for a third state. |+| 7 | A0 | input | I2C slave-address select bit 0. Tie to GND or V+ to set the corresponding address bit. May be left floating on the TMP75 for a third state. |+| 8 | V+ | power_in | Positive supply voltage input, 2.7 V to 5.5 V (absolute max 6.5 V on TMP75). Quiescent current typically 50 µA active, 0.1 µA in shutdown. A 0.01 µF bypass capacitor to GND is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Digital temperature sensor (I2C / SMBus) |+| Resolution | 12-bit (0.0625 °C) |+| Accuracy | ±1 °C typ |+| Interface | I2C / SMBus, address pins A0-A2 |+| Alert | Programmable ALERT / OS output |+| Supply voltage | 2.7-5.5 V |+| Form factor | LM75-compatible pinout |+| Package | SOIC-8 |+| Body (L×W×H) | 4.9 × 3.9 × 1.75 mm |++## Ordering variants++- `TMP75AID (SOIC-8, tube)`+- `TMP75AIDR (SOIC-8, tape & reel)`++## CAD (KiCad official)++- Symbol: `Sensor_Temperature:TMP1075D (pin-identical to TMP75)`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmp75.pdf) (35 pp, sha256 `30ddeda575764440`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude) — every pin and dimension is cited to a datasheet page; refuses to fabricate.+- **CAD:** KiCad official libraries (CC-BY-SA 4.0).++[Datasheet PDF](docs/tmp75-datasheet.pdf)
