mc33074dr2g.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

Pinout

Pin Name Type Function
1 Output 1 output Output of amplifier 1. All-NPN output stage with no deadband crossover distortion; swings from approximately VEE+0.1 V to VCC-0.9 V into a 2 kOhm load. Short-circuit current typ 30 mA source/sink.
2 Input 1- input Inverting input of amplifier 1. High-impedance Darlington input; typ input bias current 100 nA, differential input resistance 150 MOhm. Common-mode range VEE to VCC-1.8 V.
3 Input 1+ input Non-inverting input of amplifier 1. High-impedance Darlington input; typ input bias current 100 nA. Common-mode range includes ground (VEE to VCC-1.8 V).
4 VCC power_in Positive supply rail. Operates from 3.0 V single supply up to 44 V total (from VEE to VCC). Supply current per amplifier typ 1.9 mA at +/-15 V.
5 Input 2+ input Non-inverting input of amplifier 2. Darlington input stage; common-mode range includes ground (VEE to VCC-1.8 V).
6 Input 2- input Inverting input of amplifier 2. Darlington input stage; typ input bias current 100 nA.

CAD (KiCad official)

  • Symbol: MC33074DR2G
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: mc33074dr2g-etched.step / mc33074dr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc33074dr2g.step / mc33074dr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc33074dr2g.step 195 KB You want the bare part, or you mark your own boards.
mc33074dr2g-etched.step 2.7 MB You want the part with MC33074DR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 677 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.

Provenance
