MC33074DR2G 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	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.
7	Output 2	output	Output of amplifier 2. All-NPN output stage; typ short-circuit current 30 mA source/sink; drives capacitive loads up to 10,000 pF.
8	Output 3	output	Output of amplifier 3. All-NPN output stage; typ short-circuit current 30 mA source/sink.
9	Input 3-	input	Inverting input of amplifier 3. Darlington input stage; typ input bias current 100 nA.
10	Input 3+	input	Non-inverting input of amplifier 3. Darlington input stage; common-mode range includes ground.
11	VEE	power_in	Negative supply rail (or GND in single-supply operation). Supply-voltage range 3.0 V to 44 V total (VCC-VEE). Tie to ground for single-supply operation.
12	Input 4+	input	Non-inverting input of amplifier 4. Darlington input stage; common-mode range includes ground.
13	Input 4-	input	Inverting input of amplifier 4. Darlington input stage; typ input bias current 100 nA.
14	Output 4	output	Output of amplifier 4. All-NPN output stage; typ short-circuit current 30 mA source/sink; drives capacitive loads up to 10,000 pF.

3D model downloads

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.
