MC34074DR2G

onsemi · Operational Amplifier · SOIC-14

MC34074DR2G from onsemi, 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 OUT1 output Amplifier 1 output. All-NPN output stage with no deadband crossover; sources up to 30 mA typ / sinks 30 mA typ into a short.
2 IN1- input Amplifier 1 inverting input. High-impedance Darlington input (~150 MOhm differential). Input voltage must not exceed VCC or VEE.
3 IN1+ input Amplifier 1 non-inverting input. Common-mode range extends from VEE up to (VCC - 1.8 V).
4 VCC power_in Positive supply. 3.0 V to 44 V single-supply, or up to +22 V with split supplies (VCC +
5 IN2+ input Amplifier 2 non-inverting input. Common-mode range extends from VEE up to (VCC - 1.8 V).
6 IN2- input Amplifier 2 inverting input. High-impedance Darlington input; do not exceed VCC or VEE.
7 OUT2 output Amplifier 2 output. All-NPN output stage with indefinite short-circuit protection.
8 OUT3 output Amplifier 3 output. All-NPN output stage with indefinite short-circuit protection.
9 IN3- input Amplifier 3 inverting input. High-impedance Darlington input; do not exceed VCC or VEE.
10 IN3+ input Amplifier 3 non-inverting input. Common-mode range extends from VEE up to (VCC - 1.8 V).
11 VEE power_in Negative supply / ground return. Tie to GND for single-supply operation, or to a negative rail for split supplies. Total supply span VCC-VEE <= 44 V.
12 IN4+ input Amplifier 4 non-inverting input. Common-mode range extends from VEE up to (VCC - 1.8 V).
13 IN4- input Amplifier 4 inverting input. High-impedance Darlington input; do not exceed VCC or VEE.
14 OUT4 output Amplifier 4 output. All-NPN output stage with indefinite short-circuit protection.

CAD (KiCad official)

  • Symbol: MC34074DR2G
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: mc34074dr2g-etched.step / mc34074dr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc34074dr2g.step / mc34074dr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc34074dr2g.step 195 KB You want the bare part, or you mark your own boards.
mc34074dr2g-etched.step 2.6 MB You want the part with MC34074DR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 648 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

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

  • Datasheet: onsemi datasheet (30 pp, sha256 db258984783ea545, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
