LM258DT from STMicroelectronics, in a SO-8. 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. Can swing from 0 V to (VCC+ - 1.5 V); short-circuit protected with output current limited to approximately 40 mA.
2	In1-	input	Inverting input of op-amp 1. Absolute input voltage range -0.3 V to 32 V; differential input range ±32 V.
3	In1+	input	Non-inverting input of op-amp 1. Common-mode range includes the negative supply (Vcc-/GND).
4	Vcc-	power_in	Negative supply rail (or ground in single-supply operation). Total supply voltage (Vcc+ to Vcc-) up to ±16 V or 32 V single-supply.
5	In2+	input	Non-inverting input of op-amp 2. Common-mode range includes the negative supply (Vcc-/GND).
6	In2-	input	Inverting input of op-amp 2. Absolute input voltage range -0.3 V to 32 V; differential input range ±32 V.
7	Out2	output	Output of op-amp 2. Can swing from 0 V to (VCC+ - 1.5 V); short-circuit protected with output current limited to approximately 40 mA.
8	Vcc+	power_in	Positive supply rail. Operates from 3 V to 32 V single-supply or ±1.5 V to ±16 V split-supply.

3D model: SO-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm258dt.step`	122 KB	You want the bare part, or you mark your own boards.
`lm258dt-etched.step`	1.5 MB	You want the part with `LM258DT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 387 faces against 147 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.
