LM75BDP-MS from MSKSEMI, 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	I2C serial data line. Open-drain bidirectional data pin; requires an external pull-up (typ. 10 kΩ) to VCC. VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC; VOL ≤ 0.4 V at IOL = 3 mA.
2	SCL	input	I2C serial clock input from the bus master. Supports 20 Hz to 400 kHz (Fast-mode). Requires an external pull-up (typ. 10 kΩ) to VCC. Must not be left floating.
3	OS	output	Overtemperature Shutdown alert output (open-drain). Asserts when the measured temperature exceeds the programmable TTH(OTS) threshold (default 80°C) and clears when it drops below THYS (default 75°C). Configurable as comparator or interrupt mode; requires a pull-up to VCC. VOL ≤ 0.4 V at IOL = 3 mA; max sink 10 mA.
4	GND	power_in	Device ground reference (0 V).
5	A2	input	I2C slave-address user bit 2. Tie to GND or VCC to set the lower three bits of the 7-bit I2C slave address (upper 4 bits fixed at 1001b). Must not be left floating; VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC (150 mV hysteresis).
6	A1	input	I2C slave-address user bit 1. Tie to GND or VCC to set the address. Must not be left floating; VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC (150 mV hysteresis).
7	A0	input	I2C slave-address user bit 0. Tie to GND or VCC to set the address. Must not be left floating; VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC (150 mV hysteresis).
8	VCC	power_in	Supply voltage input, 2.8 V to 5.5 V (absolute max 6 V). Typical IDD ≈ 100 µA (active), ~0.2 µA in shutdown. Decouple to GND with a 0.1 µF ceramic capacitor.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm75bdp-ms.step`	123 KB	You want the bare part, or you mark your own boards.
`lm75bdp-ms-etched.step`	1.8 MB	You want the part with `LM75BDP-MS` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 461 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
