**Analog Devices Inc Maxim Integrated** · Temperature Sensors · MSOP-8

DS75U+T&R from Analog Devices Inc Maxim Integrated, in a MSOP-8. 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 | Data input/output pin for the 2-wire serial communication port. Open-drain; requires an external pullup resistor to VDD. |
| 2 | SCL | input | Clock input pin for the 2-wire serial communication port. Maximum SCL frequency is 400 kHz. |
| 3 | O.S. | output | Thermostat output. Open-drain output that asserts when the measured temperature exceeds the user-programmable TOS trip point; polarity and comparator/interrupt mode are configurable. Sinks up to 4 mA (VOL ≤ 0.8 V). |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | A2 | input | Address input pin. Combined with A1 and A0 to set the least-significant three bits of the 7-bit slave address (1001_A2A1A0), allowing up to eight DS75 devices on one 2-wire bus. |
| 6 | A1 | input | Address input pin. Combined with A2 and A0 to set the least-significant three bits of the 7-bit slave address. |
| 7 | A0 | input | Address input pin. Combined with A2 and A1 to set the least-significant three bits of the 7-bit slave address. |
| 8 | VDD | power_in | Supply voltage pin. Operating range +2.7 V to +5.5 V. Standby current ≤1 µA; active current ≤1000 µA during conversions. |

## CAD (KiCad official)

- Symbol: `DS75U+T&R`
- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`
- 3D model: MSOP-8 (KiCad packages3D, STEP)
- 3D model files: `ds75u-t-r-etched.step` / `ds75u-t-r-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ds75u-t-r.step` / `ds75u-t-r.glb` are the bare package body.
