TL084IDT from STMicroelectronics, 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.
2	IN1-	input	Amplifier 1 inverting input (JFET gate, very high input impedance).
3	IN1+	input	Amplifier 1 non-inverting input (JFET gate, very high input impedance).
4	VCC+	power_in	Positive supply. Total supply range 6 V to 36 V (±3 V to ±18 V), absolute max ±18 V.
5	IN2+	input	Amplifier 2 non-inverting input (JFET gate, very high input impedance).
6	IN2-	input	Amplifier 2 inverting input (JFET gate, very high input impedance).
7	OUT2	output	Amplifier 2 output.
8	OUT3	output	Amplifier 3 output.
9	IN3-	input	Amplifier 3 inverting input (JFET gate, very high input impedance).
10	IN3+	input	Amplifier 3 non-inverting input (JFET gate, very high input impedance).
11	VCC-	power_in	Negative supply (or GND in single-supply operation). Absolute max ±18 V with respect to VCC+ midpoint.
12	IN4+	input	Amplifier 4 non-inverting input (JFET gate, very high input impedance).
13	IN4-	input	Amplifier 4 inverting input (JFET gate, very high input impedance).
14	OUT4	output	Amplifier 4 output.

CAD (KiCad official)

3D model: SOIC-14 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tl084idt.step`	195 KB	You want the bare part, or you mark your own boards.
`tl084idt-etched.step`	1.8 MB	You want the part with `TL084IDT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 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.
