AS393MTR-G1 from Diodes Incorporated, in a SOIC-8. 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	OUTPUT1	output	Open-drain output of comparator 1. Requires external pull-up resistor to VCC (or another rail up to 36V). Sinks up to ~16 mA when the non-inverting input is below the inverting input.
2	OUTPUT2	output	Open-drain output of comparator 2. Requires external pull-up resistor to VCC (or another rail up to 36V). Sinks up to ~16 mA when the non-inverting input is below the inverting input.
3	VCC	power_in	Positive supply. Single-supply range 2V to 36V; dual-supply range ±1V to ±18V. Supply current typically 0.4 mA (both comparators).
4	IN1-	input	Inverting input of comparator 1. Common-mode input range extends from GND (V-) to VCC - 1.5V. Input offset voltage typically ±1 mV.
5	IN1+	input	Non-inverting input of comparator 1. Common-mode input range extends from GND (V-) to VCC - 1.5V. Input offset voltage typically ±1 mV.
6	IN2-	input	Inverting input of comparator 2. Common-mode input range extends from GND (V-) to VCC - 1.5V. Input offset voltage typically ±1 mV.
7	IN2+	input	Non-inverting input of comparator 2. Common-mode input range extends from GND (V-) to VCC - 1.5V. Input offset voltage typically ±1 mV.
8	GND	power_in	Negative supply / ground. Tie to system ground in single-supply operation, or to the negative rail in dual-supply operation.
