tmp275aidr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TMP275AIDR

Texas Instruments · Temperature and Humidity Sensor · SOIC-8

TMP275AIDR 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 I2C/SMBus serial data. Open-drain bidirectional line; requires an external pullup resistor (typ. 5 kΩ) to V+. VOL = 0.15 V typ at IOL = 3 mA.
2 SCL input I2C/SMBus serial clock input. Open-drain; requires an external pullup resistor to V+. Supports Fast (400 kHz) and High-Speed (up to 2.38 MHz) modes.
3 ALERT output Overtemperature alert output. Open-drain; requires an external pullup resistor. VOL = 0.15 V typ at IOL = 4 mA. Asserts when the measured temperature exceeds the programmed limit per the SMBus alert function.
4 GND power_in Device ground return.
5 A2 input I2C address select bit 2. Connect to GND or V+ to set one of the eight possible slave addresses.
6 A1 input I2C address select bit 1. Connect to GND or V+ to set one of the eight possible slave addresses.
7 A0 input I2C address select bit 0. Connect to GND or V+ to set one of the eight possible slave addresses.
8 V+ power_in Positive supply, 2.7 V to 5.5 V (7 V absolute max). Bypass with a 0.01 µF (or larger) ceramic capacitor to GND close to the pin. Typical IQ = 50 µA (bus inactive).

CAD (KiCad official)

  • Symbol: TMP275AIDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tmp275aidr-etched.step / tmp275aidr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmp275aidr.step / tmp275aidr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tmp275aidr.step 122 KB You want the bare part, or you mark your own boards.
tmp275aidr-etched.step 1.8 MB You want the part with TMP275AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 459 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (34 pp, sha256 dc06223f8413fc81, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
