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 + |VEE| <= 44 V). ~1.9 mA quiescent per amplifier at +/-15 V. |+| 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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++- `MC34074DR2GDR2G`+- `MC34074DR2GDG`+- `MC34074DR2GPG`+- `MC34074DR2GDTBR2G`++## CAD (KiCad official)++- Symbol: `MC34074DR2G`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc34074-d.pdf) (30 pp, sha256 `db258984783ea545`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
