MAX9018AEKA+T from Analog Devices Inc./Maxim Integrated, in a SOT-23-8. 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	Comparator A open-drain output that requires an external pullup resistor and can be pulled up to 5.5V above VEE, beyond VCC.
2	REF/INA-	output	1.24V reference output that is internally connected to the inverting input of comparator A, and can source and sink up to 100nA to external circuitry.
3	INA+	input	Comparator A noninverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
4	VEE	power_in	Negative supply voltage, normally ground.
5	INB+	input	Comparator B noninverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
6	INB-	input	Comparator B inverting input with a common-mode range from VEE - 0.2V to VCC + 0.2V.
7	OUTB	output	Comparator B open-drain output that requires an external pullup resistor and can be pulled up to 5.5V above VEE, beyond VCC.
8	VCC	power_in	Positive supply voltage, 1.8V to 5.5V operating range, with absolute maximum of 6V between VCC and VEE.
