LMV393IDR from Texas Instruments, in a SOIC-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	1OUT	output	Comparator 1 output. Open-collector; requires an external pull-up resistor to VCC+ (or another rail up to VCC+ +0.3V). Sinks up to 23mA typical with VSAT ≈ 150mV at 1.5mA.
2	1IN-	input	Comparator 1 inverting input. Common-mode range −0.1V to (VCC+ − ~1V); IB ≈ 5nA typical (250nA max at 25°C).
3	1IN+	input	Comparator 1 non-inverting input. Common-mode range −0.1V to (VCC+ − ~1V); differential input voltage rated ±5.5V.
4	GND	power_in	Device ground / negative supply rail. Return for both comparator channels; must be the reference for all input voltage measurements.
5	2IN+	input	Comparator 2 non-inverting input. Common-mode range −0.1V to (VCC+ − ~1V); differential input voltage rated ±5.5V.
6	2IN-	input	Comparator 2 inverting input. Common-mode range −0.1V to (VCC+ − ~1V); IB ≈ 5nA typical (250nA max at 25°C).
7	2OUT	output	Comparator 2 output. Open-collector; requires an external pull-up resistor. Output leakage ≤1µA over temp; sinks up to 23mA typical.
8	VCC+	power_in	Positive supply rail. Recommended 2.7V to 5.5V single-supply operation; absolute max 5.5V. Typical supply current 50µA (140µA max) for both comparators.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv393idr.step`	122 KB	You want the bare part, or you mark your own boards.
`lmv393idr-etched.step`	1.9 MB	You want the part with `LMV393IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 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.
