**onsemi** · Operational Amplifier · TSSOP-14

MC33074DTBR2G from onsemi, in a TSSOP-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 | Output of op-amp 1. All-NPN output stage with source/sink short-circuit protection, drives up to +/-14 V with +/-15 V supplies into 2 kOhm. |
| 2 | IN1- | input | Inverting input of op-amp 1. High-impedance Darlington input (Rin ~150 MOhm, Cin ~2.5 pF); input bias current typ 100 nA. |
| 3 | IN1+ | input | Non-inverting input of op-amp 1. Common-mode range includes VEE (ground), extends to (VCC - 1.8 V). |
| 4 | VCC | power_in | Positive supply. Total supply (VCC - VEE) 3.0 V to 44 V; quiescent current typ 1.9 mA per amplifier at +/-15 V. |
| 5 | IN2+ | input | Non-inverting input of op-amp 2. |
| 6 | IN2- | input | Inverting input of op-amp 2. |
| 7 | OUT2 | output | Output of op-amp 2. |
| 8 | OUT3 | output | Output of op-amp 3. |
| 9 | IN3- | input | Inverting input of op-amp 3. |
| 10 | IN3+ | input | Non-inverting input of op-amp 3. |
| 11 | VEE | power_in | Negative supply / ground. Tie to GND for single-supply operation; input common-mode range extends down to this rail. |
| 12 | IN4+ | input | Non-inverting input of op-amp 4. |
| 13 | IN4- | input | Inverting input of op-amp 4. |
| 14 | OUT4 | output | Output of op-amp 4. |
