LMV393MMX from Texas Instruments, in a MSOP-8. 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	OUT A	output	Open-drain comparator A output. Requires an external pull-up resistor to VCC or a separate logic rail (up to VCC).
2	-IN A	input	Inverting input of comparator A. Input common-mode range extends from V- (GND) to VCC - 1.5 V.
3	+IN A	input	Non-inverting input of comparator A. Input common-mode range extends from V- (GND) to VCC - 1.5 V.
4	GND	power_in	Negative supply / ground. Ground reference; V- pin. Total supply 2.7 V to 5.5 V referenced from VCC to GND.
5	+IN B	input	Non-inverting input of comparator B. Input common-mode range extends from V- (GND) to VCC - 1.5 V.
6	-IN B	input	Inverting input of comparator B. Input common-mode range extends from V- (GND) to VCC - 1.5 V.
7	OUT B	output	Open-drain comparator B output. Requires an external pull-up resistor to VCC or a separate logic rail (up to VCC).
8	VCC	power_in	Positive supply rail. Operating range 2.7 V to 5.5 V (single supply) or ±1.35 V to ±2.75 V (dual supply). Bypass with 0.1 µF close to the pin.

Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
3D model: MSOP-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv393mmx.step`	123 KB	You want the bare part, or you mark your own boards.
`lmv393mmx-etched.step`	1.8 MB	You want the part with `LMV393MMX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 453 faces against 147 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.
