TL084CDT 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	Output of op-amp 1. Push-pull output with short-circuit protection; output voltage swing typically +/-12 V into 2 kOhm at Vcc = +/-15 V.
2	IN1-	input	Inverting input of op-amp 1. High-impedance JFET input (~10^12 Ohm), input bias current ~20 pA typ at 25 C.
3	IN1+	input	Non-inverting input of op-amp 1. High-impedance JFET input. Common-mode range typically +11 V to -12 V at Vcc = +/-15 V.
4	VCC+	power_in	Positive supply rail. Operating range 6 V to 36 V total (single supply) or up to +/-18 V split supply. Absolute maximum +/-18 V. Supply current ~1.4 mA typ (no load).
5	IN2+	input	Non-inverting input of op-amp 2. High-impedance JFET input.
6	IN2-	input	Inverting input of op-amp 2. High-impedance JFET input.
7	OUT2	output	Output of op-amp 2. Short-circuit protected; output short-circuit current ~40 mA typ.
8	OUT3	output	Output of op-amp 3. Short-circuit protected push-pull output.
9	IN3-	input	Inverting input of op-amp 3. High-impedance JFET input.
10	IN3+	input	Non-inverting input of op-amp 3. High-impedance JFET input.
11	VCC-	power_in	Negative supply rail (or GND in single-supply operation). Absolute maximum -18 V relative to VCC+ midpoint. In single-supply operation, tie to GND.
12	IN4+	input	Non-inverting input of op-amp 4. High-impedance JFET input.
13	IN4-	input	Inverting input of op-amp 4. High-impedance JFET input.
14	OUT4	output	Output of op-amp 4. Short-circuit protected push-pull output.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tl084cdt.step`	195 KB	You want the bare part, or you mark your own boards.
`tl084cdt-etched.step`	1.9 MB	You want the part with `TL084CDT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 489 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.
