MC33074ADR2G 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; typical output swing 13.6 V at VCC=+15 V / VEE=-15 V with RL=2 kOhm; source/sink short-circuit current ~30 mA typical.
2	IN1-	input	Amplifier 1 inverting input. Differential input voltage should not exceed
3	IN1+	input	Amplifier 1 non-inverting input. Common-mode range VEE to (VCC-1.8 V); input voltage should not exceed
4	VCC	power_in	Positive supply rail. Single-supply operation 3.0 V to 44 V, or split supply with
5	IN2+	input	Amplifier 2 non-inverting input. Common-mode range VEE to (VCC-1.8 V).
6	IN2-	input	Amplifier 2 inverting input. Typical input bias current 100 nA; input offset current 6 nA typical.
7	OUT2	output	Amplifier 2 output. Indefinite short-circuit protection; drives capacitive loads up to 10,000 pF.
8	OUT3	output	Amplifier 3 output. Same characteristics as OUT1/OUT2.
9	IN3-	input	Amplifier 3 inverting input.
10	IN3+	input	Amplifier 3 non-inverting input. Common-mode range VEE to (VCC-1.8 V).
11	VEE	power_in	Negative supply rail (or GND in single-supply operation). Total supply
12	IN4+	input	Amplifier 4 non-inverting input.
13	IN4-	input	Amplifier 4 inverting input.
14	OUT4	output	Amplifier 4 output. Same characteristics as the other three outputs.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33074adr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc33074adr2g-etched.step`	2.8 MB	You want the part with `MC33074ADR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 703 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.
