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 | Output 1 | output | Amplifier 1 output. All-NPN output stage sourcing/sinking up to 30 mA typ (10 mA source / 20 mA sink min short-circuit). Swings to within ~1.0 V of VCC and ~0.3 V of VEE with 10 kΩ load. |+| 2 | In-1 | input | Amplifier 1 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ, differential input resistance ~150 MΩ, input capacitance ~2.5 pF. |+| 3 | In+1 | input | Amplifier 1 non-inverting input. Common-mode range includes VEE up to (VCC − 1.8 V); do not exceed VCC or drive below VEE − 0.3 V. |+| 4 | VCC | power_in | Positive supply rail. Single-supply operation 3.0 V to 44 V, or split supplies with VCC + |VEE| ≤ 44 V. Supply current ≈ 1.9 mA typ per amplifier (7.6 mA typ total for the quad) at ±15 V. Bypass with a decoupling capacitor immediately adjacent to the pin. |+| 5 | In+2 | input | Amplifier 2 non-inverting input. Same VICR/IIB characteristics as amplifier 1. |+| 6 | In-2 | input | Amplifier 2 inverting input. Bipolar Darlington input; IIB ≈ 100 nA typ. |+| 7 | Output 2 | output | Amplifier 2 output. All-NPN output stage, 30 Ω typ open-loop output impedance at 1 MHz; drives 0 pF to 10,000 pF capacitive loads without oscillation in unity gain. |+| 8 | Output 3 | output | Amplifier 3 output. All-NPN output stage; 20 mA min sink capability typically to (VEE + 1.8 V). |+| 9 | In-3 | input | Amplifier 3 inverting input. Bipolar Darlington input stage; ESD-protected input diodes/clamps. |+| 10 | In+3 | input | Amplifier 3 non-inverting input. Common-mode input voltage range VEE to (VCC − 1.8 V) at 25 °C. |+| 11 | VEE | power_in | Negative supply / ground return. Tie to ground for single-supply operation (3.0 V to 44 V at VCC) or to a negative rail for split supplies. VCC to VEE differential must not exceed +44 V. |+| 12 | In+4 | input | Amplifier 4 non-inverting input. Same input characteristics as the other channels. |+| 13 | In-4 | input | Amplifier 4 inverting input. Bipolar Darlington input; VIO ≤ 3.0 mV max (A suffix) at 25 °C. |+| 14 | Output 4 | output | Amplifier 4 output. All-NPN output stage; short-circuit protected indefinitely to ground at ±15 V supplies. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TSSOP-14 |+| Category | Op-amp/Cmp |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `MC33074ADTBR2GDTBG`+- `MC33074ADTBR2G`+- `MC33074ADTBG`+- `MC33074ADTBR2GPG`+- `MC33074ADTBR2GAPG`+- `MC33074ADTBR2GVPG`+- `MC33074ADTBR2GDG`+- `MC33074ADTBR2GADG`+- `MC33074ADTBR2GDR2G`+- `MC33074ADTBR2GADR2G`+- `MC33074ADTBR2GVDG`+- `MC33074ADTBR2GVDR2G`+- `MC33074ADTBR2GMTTBG`++## CAD (KiCad official)++- Symbol: `MC33074ADTBR2G`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc33074adtbr2-d.pdf) (None pp, sha256 `bac1389f1389705f`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
