# TMP75CQDGKRQ1

**Texas Instruments** · Temperature Sensors · VSSOP-8-0.65mm

TMP75CQDGKRQ1 from Texas Instruments, in a VSSOP-8-0.65mm. 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 | SDA | bidirectional | Serial data line; open-drain output that requires a pull-up resistor. |
| 2 | SCL | input | Serial clock input for the two-wire bus. |
| 3 | ALERT | output | Overtemperature alert; open-drain output that requires a pull-up resistor. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | A2 | input | Address select input; connect to GND or VS. |
| 6 | A1 | input | Address select input; connect to GND or VS. |
| 7 | A0 | input | Address select input; connect to GND or VS. |
| 8 | VS | power_in | Supply voltage input, 1.4 V to 3.6 V. |
