tlc27l4cdr.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 -> 14 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

Texas Instruments · Operational Amplifier · SOIC-14

TLC27L4CDR from Texas Instruments, in a SOIC-14. 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 op-amp channel 1. Output voltage range includes the negative rail.
2 1IN- input Inverting input of op-amp channel 1. High input impedance (~10^12 Ω typ).
3 1IN+ input Non-inverting input of op-amp channel 1. Common-mode range extends below the negative rail (C/I suffix types).
4 VDD power_in Positive supply voltage. Recommended operating range 3 V to 16 V (C suffix), 4 V to 16 V (I/M suffix). Absolute maximum 18 V.
5 2IN+ input Non-inverting input of op-amp channel 2. High input impedance (~10^12 Ω typ).
6 2IN- input Inverting input of op-amp channel 2. High input impedance (~10^12 Ω typ).
7 2OUT output Output of op-amp channel 2. Output voltage range includes the negative rail.
8 3OUT output Output of op-amp channel 3. Output voltage range includes the negative rail.
9 3IN- input Inverting input of op-amp channel 3. High input impedance (~10^12 Ω typ).
10 3IN+ input Non-inverting input of op-amp channel 3. High input impedance (~10^12 Ω typ).
11 GND power_in Ground / negative supply. All voltages referenced to network ground. Total current out of GND rated 45 mA maximum.
12 4IN+ input Non-inverting input of op-amp channel 4. High input impedance (~10^12 Ω typ).
13 4IN- input Inverting input of op-amp channel 4. High input impedance (~10^12 Ω typ).
14 4OUT output Output of op-amp channel 4. Output voltage range includes the negative rail.

CAD (KiCad official)

  • Symbol: TLC27L4CDR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: tlc27l4cdr-etched.step / tlc27l4cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc27l4cdr.step / tlc27l4cdr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlc27l4cdr.step 195 KB You want the bare part, or you mark your own boards.
tlc27l4cdr-etched.step 2.0 MB You want the part with TLC27L4CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 faces against 237 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.
