AS393MTR-E1 from Diodes Incorporated, 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	OUTPUT1	output	Open-collector output of comparator 1, which needs an external pull-up; it sinks at least 6.0mA with a typical saturation voltage of 200mV at 4mA.
2	INPUT1-	input	Inverting input of comparator 1; the common-mode voltage must not go below -0.3V at +25°C and the upper limit is VCC-1.5V, though the input can withstand up to +36V without damage.
3	INPUT1+	input	Non-inverting input of comparator 1; the common-mode voltage must not go below -0.3V at +25°C and the upper limit is VCC-1.5V, though the input can withstand up to +36V without damage.
4	GND	power_in	Ground reference (0V) for the device, used as the negative supply in single-supply operation.
5	INPUT2+	input	Non-inverting input of comparator 2; the common-mode voltage must not go below -0.3V at +25°C and the upper limit is VCC-1.5V, though the input can withstand up to +36V without damage.
6	INPUT2-	input	Inverting input of comparator 2; the common-mode voltage must not go below -0.3V at +25°C and the upper limit is VCC-1.5V, though the input can withstand up to +36V without damage.
7	OUTPUT2	output	Open-collector output of comparator 2, which needs an external pull-up; it sinks at least 6.0mA with a typical saturation voltage of 200mV at 4mA.
8	VCC	power_in	Positive supply pin; single supply 2V to 36V (or dual supplies ±1.0V to ±18V).
