LM248DR from Texas Instruments, 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	1OUT	output	Output of op-amp channel 1.
2	1IN-	input	Inverting input of op-amp channel 1.
3	1IN+	input	Non-inverting input of op-amp channel 1.
4	V+	power_in	Positive supply. Operating range ±3 V to ±18 V split, or 6 V to 36 V single supply.
5	2IN+	input	Non-inverting input of op-amp channel 2.
6	2IN-	input	Inverting input of op-amp channel 2.
7	2OUT	output	Output of op-amp channel 2.
8	3OUT	output	Output of op-amp channel 3.
9	3IN-	input	Inverting input of op-amp channel 3.
10	3IN+	input	Non-inverting input of op-amp channel 3.
11	V-	power_in	Negative supply. Tie to ground for single-supply operation, or to a negative rail for split-supply operation (±3 V to ±18 V).
12	4IN+	input	Non-inverting input of op-amp channel 4.
13	4IN-	input	Inverting input of op-amp channel 4.
14	4OUT	output	Output of op-amp channel 4.

CAD (KiCad official)

Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
3D model: SOIC-14 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm248dr.step`	195 KB	You want the bare part, or you mark your own boards.
`lm248dr-etched.step`	1.9 MB	You want the part with `LM248DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 481 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.
