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). |
