TLC2274AIDR 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. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). Short-circuit protected to either supply rail.
2	1IN-	input	Inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Input voltage range V(DD-) to V(DD+) - 1.5 V (common-mode).
3	1IN+	input	Non-inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Common-mode range includes the negative rail.
4	VDD+	power_in	Positive (highest) supply rail. Operating range ±2.2 V to ±8 V split, or up to 16 V single-supply relative to VDD-. Absolute max 8 V vs midpoint.
5	2IN+	input	Non-inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA.
6	2IN-	input	Inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA.
7	2OUT	output	Output of op-amp channel 2. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.
8	3OUT	output	Output of op-amp channel 3. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.
9	3IN-	input	Inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA.
10	3IN+	input	Non-inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA.
11	VDD-	power_in	Negative (lowest) supply rail. Tie to GND for single-supply operation, or to a negative rail for split-supply. Absolute max -8 V vs midpoint.
12	4IN+	input	Non-inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA.
13	4IN-	input	Inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA.
14	4OUT	output	Output of op-amp channel 4. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2274aidr.step`	195 KB	You want the bare part, or you mark your own boards.
`tlc2274aidr-etched.step`	2.1 MB	You want the part with `TLC2274AIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 556 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.
