TLC27L4CDR 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. Output voltage range includes the negative rail.
2	1IN-	input	Inverting input of op-amp channel 1. High input impedance (~10^12 Ω typ).
3	1IN+	input	Non-inverting input of op-amp channel 1. Common-mode range extends below the negative rail (C/I suffix types).
4	VDD	power_in	Positive supply voltage. Recommended operating range 3 V to 16 V (C suffix), 4 V to 16 V (I/M suffix). Absolute maximum 18 V.
5	2IN+	input	Non-inverting input of op-amp channel 2. High input impedance (~10^12 Ω typ).
6	2IN-	input	Inverting input of op-amp channel 2. High input impedance (~10^12 Ω typ).
7	2OUT	output	Output of op-amp channel 2. Output voltage range includes the negative rail.
8	3OUT	output	Output of op-amp channel 3. Output voltage range includes the negative rail.
9	3IN-	input	Inverting input of op-amp channel 3. High input impedance (~10^12 Ω typ).
10	3IN+	input	Non-inverting input of op-amp channel 3. High input impedance (~10^12 Ω typ).
11	GND	power_in	Ground / negative supply. All voltages referenced to network ground. Total current out of GND rated 45 mA maximum.
12	4IN+	input	Non-inverting input of op-amp channel 4. High input impedance (~10^12 Ω typ).
13	4IN-	input	Inverting input of op-amp channel 4. High input impedance (~10^12 Ω typ).
14	4OUT	output	Output of op-amp channel 4. Output voltage range includes the negative rail.

CAD (KiCad official)

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc27l4cdr.step`	195 KB	You want the bare part, or you mark your own boards.
`tlc27l4cdr-etched.step`	2.0 MB	You want the part with `TLC27L4CDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 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.
