TSV914IPT from UMW, 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	OUT1	output	Amplifier 1 output. Rail-to-rail; can source/sink up to 35 mA (typ).
2	IN1-	input	Amplifier 1 inverting input. Rail-to-rail common-mode range (VCC- − 0.1 V to VCC+ + 0.1 V).
3	IN1+	input	Amplifier 1 non-inverting input. Rail-to-rail common-mode range (VCC- − 0.1 V to VCC+ + 0.1 V).
4	VCC+	power_in	Positive supply rail. Operating range 2.5 V to 5.5 V (2.3 V to 5.5 V at 0 °C < Top < 125 °C). Absolute maximum 6 V.
5	IN2+	input	Amplifier 2 non-inverting input. Rail-to-rail common-mode range.
6	IN2-	input	Amplifier 2 inverting input. Rail-to-rail common-mode range.
7	OUT2	output	Amplifier 2 output. Rail-to-rail; 35 mA typical drive.
8	OUT3	output	Amplifier 3 output. Rail-to-rail; 35 mA typical drive.
9	IN3-	input	Amplifier 3 inverting input. Rail-to-rail common-mode range.
10	IN3+	input	Amplifier 3 non-inverting input. Rail-to-rail common-mode range.
11	VCC-	power_in	Negative supply rail (ground in single-supply operation). Vid must not exceed ±VCC; VCC+ − VCC- ≤ 6 V absolute max.
12	IN4+	input	Amplifier 4 non-inverting input. Rail-to-rail common-mode range.
13	IN4-	input	Amplifier 4 inverting input. Rail-to-rail common-mode range.
14	OUT4	output	Amplifier 4 output. Rail-to-rail; 35 mA typical drive.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tsv914ipt.step`	194 KB	You want the bare part, or you mark your own boards.
`tsv914ipt-etched.step`	1.9 MB	You want the part with `TSV914IPT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 497 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.
