MCP6561T-E from Microchip, in a SC-70-5. 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	output	Push-pull comparator output. CMOS/TTL-compatible, rail-to-rail: VOH >= VDD-0.7V at IOUT=-3/-8 mA, VOL <= 0.6V at IOUT=3/8 mA (VDD=1.8V/5.5V). Short-circuit current typ +/-30 mA; limit continuous IOUT to <=50 mA.
2	VSS	power_in	Negative supply / ground reference. Absolute maximum VDD-VSS = 6.5V.
3	+IN	input	Non-inverting analog comparator input. Rail-to-rail common-mode range VSS-0.3V to VDD+0.3V. Input bias current ~1 pA typ at 25 degC; abs max current at input pins +/-2 mA.
4	-IN	input	Inverting analog comparator input. Rail-to-rail common-mode range VSS-0.3V to VDD+0.3V. Input offset voltage +/-3 mV typ (+/-10 mV max); input hysteresis 1-5 mV.
5	VDD	power_in	Positive supply. Operating range 1.8V to 5.5V; quiescent current 100 uA typ (130 uA max) per comparator. PSRR 70 dB typ.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mcp6561t-e.step`	87 KB	You want the bare part, or you mark your own boards.
`mcp6561t-e-etched.step`	1.7 MB	You want the part with `MCP6561T-E` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 433 faces against 102 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.
