TMP1075DGKR from Texas Instruments, in a VSSOP-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	I2C/SMBus serial data. Open-drain; requires an external pullup resistor (typ. 5 kΩ).
2	SCL	input	I2C/SMBus serial clock input. Requires an external pullup resistor.
3	ALERT	output	Overtemperature alert. Open-drain output that requires an external pullup resistor. Asserts when temperature crosses the programmed threshold.
4	GND	power_in	Ground reference for the device.
5	A2	input	I2C address select bit A2. Tie to GND or V+ to configure one of the device address options.
6	A1	input	I2C address select bit A1. Tie to GND, V+, SDA, or SCL to configure the device address.
7	A0	input	I2C address select bit A0. Tie to GND, V+, SDA, or SCL to configure the device address.
8	V+	power_in	Supply voltage, 1.7 V to 5.5 V (TMP1075). Bypass with a 0.01 µF capacitor to GND.
