MAX907ESA+ from Maxim Integrated, in a SOIC-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 output, TTL-compatible with no pullup needed, and it can be continuously shorted to either supply rail.
2	INA-	input	Comparator A inverting input, with a common-mode range of -0.2V to (V+ - 1.5V).
3	INA+	input	Comparator A noninverting input, with a common-mode range of -0.2V to (V+ - 1.5V).
4	GND	power_in	Ground.
5	INB+	input	Comparator B noninverting input, with a common-mode range of -0.2V to (V+ - 1.5V).
6	INB-	input	Comparator B inverting input, with a common-mode range of -0.2V to (V+ - 1.5V).
7	OUTB	output	Comparator B output, TTL-compatible with no pullup needed, and it can be continuously shorted to either supply rail.
8	V+	power_in	Positive supply, operating range 4.5V to 5.5V (absolute maximum +6V to GND), decoupled with a 0.1µF ceramic capacitor placed close to the pin.
