MC33179DR2G 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	Output of amplifier 1. NPN output stage with 600 Ω drive capability and typical ±80 mA short-circuit source current.
2	IN1-	input	Inverting input of amplifier 1. High-frequency PNP differential input; common-mode range typically -14 V to +14 V on ±15 V supplies. ESD-clamped.
3	IN1+	input	Non-inverting input of amplifier 1. High-frequency PNP differential input; input bias current typ 100 nA, offset current typ 5 nA. ESD-clamped.
4	VCC	power_in	Positive supply rail. Operates single-supply or split supply; total (VCC to VEE) up to +36 V, split ±2.0 V to ±18 V. Typical quiescent supply current 1.7 mA (quad).
5	IN2+	input	Non-inverting input of amplifier 2. High-frequency PNP differential input; ESD-clamped.
6	IN2-	input	Inverting input of amplifier 2. High-frequency PNP differential input; ESD-clamped.
7	OUT2	output	Output of amplifier 2. NPN output stage with 600 Ω drive capability.
8	OUT3	output	Output of amplifier 3. NPN output stage with 600 Ω drive capability.
9	IN3-	input	Inverting input of amplifier 3. High-frequency PNP differential input; ESD-clamped.
10	IN3+	input	Non-inverting input of amplifier 3. High-frequency PNP differential input; ESD-clamped.
11	VEE	power_in	Negative supply rail (or ground for single-supply operation). Split ±2.0 V to ±18 V; total VCC-VEE up to +36 V.
12	IN4+	input	Non-inverting input of amplifier 4. High-frequency PNP differential input; ESD-clamped.
13	IN4-	input	Inverting input of amplifier 4. High-frequency PNP differential input; ESD-clamped.
14	OUT4	output	Output of amplifier 4. NPN output stage with 600 Ω drive capability.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc33179dr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc33179dr2g-etched.step`	2.7 MB	You want the part with `MC33179DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 669 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.
