TLC2274IDR from UMW, in a SOP-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 amplifier channel 1. Rail-to-rail CMOS output, ±50 mA absolute maximum output current.
2	1IN-	input	Inverting input of amplifier channel 1. High-impedance CMOS input, typical bias current 1 pA.
3	1IN+	input	Non-inverting input of amplifier channel 1. Common-mode input range includes the negative rail.
4	VDD+	power_in	Positive (highest) supply. Absolute maximum 8 V referenced to midpoint between VDD+ and VDD-. Supplies all four amplifiers.
5	2IN+	input	Non-inverting input of amplifier channel 2. Common-mode input range includes the negative rail.
6	2IN-	input	Inverting input of amplifier channel 2. High-impedance CMOS input, typical bias current 1 pA.
7	2OUT	output	Output of amplifier channel 2. Rail-to-rail CMOS output, ±50 mA absolute maximum output current.
8	3OUT	output	Output of amplifier channel 3. Rail-to-rail CMOS output, ±50 mA absolute maximum output current.
9	3IN-	input	Inverting input of amplifier channel 3. High-impedance CMOS input, typical bias current 1 pA.
10	3IN+	input	Non-inverting input of amplifier channel 3. Common-mode input range includes the negative rail.
11	VDD-	power_in	Negative (lowest) supply / GND in single-supply operation. Absolute maximum -8 V referenced to midpoint between rails.
12	4IN+	input	Non-inverting input of amplifier channel 4. Common-mode input range includes the negative rail.
13	4IN-	input	Inverting input of amplifier channel 4. High-impedance CMOS input, typical bias current 1 pA.
14	4OUT	output	Output of amplifier channel 4. Rail-to-rail CMOS output, ±50 mA absolute maximum output current.

CAD (KiCad official)

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2274idr.step`	195 KB	You want the bare part, or you mark your own boards.
`tlc2274idr-etched.step`	2.0 MB	You want the part with `TLC2274IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 530 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.
