TSV6394AIPT 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	Op-amp 1 output. Rail-to-rail output stage; VOH/VOL within ~7 mV of rails at RL=10 kΩ.
2	In1-	input	Op-amp 1 inverting input. Rail-to-rail input common-mode range (Vcc-)-0.1 to (Vcc+)+0.1. Ib typ 1 pA.
3	In1+	input	Op-amp 1 non-inverting input. Rail-to-rail input common-mode range.
4	Vcc+	power_in	Positive supply. Operating range 1.5 to 5.5 V; absolute max 6 V. Decouple with 100 nF close to the pin.
5	In2+	input	Op-amp 2 non-inverting input. Rail-to-rail input common-mode range.
6	In2-	input	Op-amp 2 inverting input.
7	Out2	output	Op-amp 2 output. Rail-to-rail output; ~12 mA sink/10 mA source at Vcc=1.8 V.
8	Out3	output	Op-amp 3 output. Rail-to-rail output stage.
9	In3-	input	Op-amp 3 inverting input.
10	In3+	input	Op-amp 3 non-inverting input.
11	Vcc-	power_in	Negative supply / ground return. Tie to GND for single-supply operation; absolute max Vcc(+) - Vcc(-) = 6 V.
12	In4+	input	Op-amp 4 non-inverting input.
13	In4-	input	Op-amp 4 inverting input.
14	Out4	output	Op-amp 4 output. Rail-to-rail output stage.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tsv6394aipt.step`	194 KB	You want the bare part, or you mark your own boards.
`tsv6394aipt-etched.step`	2.4 MB	You want the part with `TSV6394AIPT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 613 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.
