TLV274CPWR from Texas Instruments, in a TSSOP-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	Amplifier 1 output. Rail-to-rail output stage, ±100 mA absolute-max output current, 3-MHz GBW.
2	1IN-	input	Amplifier 1 inverting input. CMOS gate, ~1 pA input bias current, 1000 GΩ differential input resistance, 8 pF common-mode input capacitance.
3	1IN+	input	Amplifier 1 non-inverting input. Common-mode input voltage range 0 V to VDD-1.35 V.
4	VDD	power_in	Positive supply rail. Recommended 2.7 V to 16 V single supply (or ±1.35 V to ±8 V split supply). Absolute maximum 16.5 V. Powers all four amplifier channels; total supply current ~4 × 550 µA typical.
5	2IN+	input	Amplifier 2 non-inverting input. Common-mode input voltage range 0 V to VDD-1.35 V.
6	2IN-	input	Amplifier 2 inverting input. CMOS gate, ~1 pA input bias current.
7	2OUT	output	Amplifier 2 output. Rail-to-rail output stage, ±100 mA absolute-max output current.
8	3OUT	output	Amplifier 3 output. Rail-to-rail output stage, ±100 mA absolute-max output current.
9	3IN-	input	Amplifier 3 inverting input. CMOS gate, ~1 pA input bias current.
10	3IN+	input	Amplifier 3 non-inverting input. Common-mode input voltage range 0 V to VDD-1.35 V.
11	GND	power_in	Negative supply / ground reference. Tied to 0 V in single-supply operation, or to the negative rail in split-supply operation. All voltages in the datasheet are referenced to GND.
12	4IN+	input	Amplifier 4 non-inverting input. Common-mode input voltage range 0 V to VDD-1.35 V.
13	4IN-	input	Amplifier 4 inverting input. CMOS gate, ~1 pA input bias current.
14	4OUT	output	Amplifier 4 output. Rail-to-rail output stage, ±100 mA absolute-max output current.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv274cpwr.step`	194 KB	You want the bare part, or you mark your own boards.
`tlv274cpwr-etched.step`	1.9 MB	You want the part with `TLV274CPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 508 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.
