TMP75AIDR from Texas Instruments, in a SOIC-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 | Serial data line for I2C/SMBus interface. Open-drain output; requires an external pull-up resistor (typically 4.7 kΩ to V+). |
| 2 | SCL | input | Serial clock input for I2C/SMBus interface. Open-drain compatible; requires an external pull-up resistor (typically 4.7 kΩ to V+). |
| 3 | ALERT | output | Over-temperature alert output (SMBus Alert). Open-drain output; requires an external pull-up resistor. Asserts when measured temperature crosses the programmed limit. |
| 4 | GND | power_in | Device ground reference. Connect to system ground. |
| 5 | A2 | input | I2C slave address select bit 2. Tie to GND or V+ to program the device address. On TMP175 this pin may also be left floating for extra address states; on TMP75 tie to a valid logic level. |
| 6 | A1 | input | I2C slave address select bit 1. Tie to GND or V+ to program the device address. On TMP175 this pin may also be left floating for extra address states. |
| 7 | A0 | input | I2C slave address select bit 0. Tie to GND or V+ to program the device address. On TMP175 this pin may also be left floating for extra address states. |
| 8 | V+ | power_in | Positive supply voltage input, 2.7 V to 5.5 V. Bypass to GND with 0.01 µF (updated recommendation in rev M) close to the pin. |
