MCP6549-E from Microchip Tech, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUTA	output	Digital output of comparator A; CMOS open-drain output that can be pulled up to as much as 10V above VSS for level shifting or wired-OR.
2	VINA-	input	Inverting input of comparator A, a high-impedance CMOS input with low bias current.
3	VINA+	input	Non-inverting input of comparator A, a high-impedance CMOS input with low bias current.
4	VDD	power_in	Positive power supply, 1.6V to 5.5V above VSS, requiring a local bypass capacitor of typically 0.01 µF to 0.1 µF within 2 mm of the pin.
5	VINB+	input	Non-inverting input of comparator B, a high-impedance CMOS input with low bias current.
6	VINB-	input	Inverting input of comparator B, a high-impedance CMOS input with low bias current.
7	OUTB	output	Digital output of comparator B; CMOS open-drain output that can be pulled up to as much as 10V above VSS for level shifting or wired-OR.
8	OUTC	output	Digital output of comparator C; CMOS open-drain output that can be pulled up to as much as 10V above VSS for level shifting or wired-OR.
9	VINC-	input	Inverting input of comparator C, a high-impedance CMOS input with low bias current.
10	VINC+	input	Non-inverting input of comparator C, a high-impedance CMOS input with low bias current.
11	VSS	power_in	Negative power supply pin, connected to ground in typical single-supply operation; other pins operate between VSS and VDD.
12	VIND+	input	Non-inverting input of comparator D, a high-impedance CMOS input with low bias current.
13	VIND-	input	Inverting input of comparator D, a high-impedance CMOS input with low bias current.
14	OUTD	output	Digital output of comparator D; CMOS open-drain output that can be pulled up to as much as 10V above VSS for level shifting or wired-OR.
