tlc272cdr.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

TLC272CDR

Texas Instruments · Operational Amplifier · SOIC-8

TLC272CDR 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 1OUT output Output of amplifier 1. Rail-to-negative output stage; VOH typ 3.8 V and VOL typ 0 mV at VDD=5 V with RL=10 kΩ. Max output current ±30 mA.
2 1IN- input Inverting input of amplifier 1. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail (down to −0.2 V at VDD=5 V).
3 1IN+ input Non-inverting input of amplifier 1. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
4 GND power_in Ground / negative supply rail (V−). Single-supply operation referenced to this pin. Total current out of GND up to 45 mA absolute max.
5 2IN+ input Non-inverting input of amplifier 2. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
6 2IN- input Inverting input of amplifier 2. High-impedance CMOS input (~10^12 Ω), IIB typ 0.6 pA at 25°C. Common-mode range extends below the negative rail.
7 2OUT output Output of amplifier 2. Rail-to-negative output stage; VOH typ 3.8 V and VOL typ 0 mV at VDD=5 V with RL=10 kΩ. Max output current ±30 mA.
8 VDD power_in Positive supply rail. Operating range 3-16 V (C-suffix) or 4-16 V (I/M-suffix); abs max 18 V. Supply current typ 1.4 mA (both amplifiers) at VDD=5 V.

CAD (KiCad official)

  • Symbol: TLC272CDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tlc272cdr-etched.step / tlc272cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc272cdr.step / tlc272cdr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlc272cdr.step 122 KB You want the bare part, or you mark your own boards.
tlc272cdr-etched.step 1.7 MB You want the part with TLC272CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 432 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.
