**XINLUDA** · Comparators · DIP-8

XD393 from XINLUDA, in a DIP-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 | 1OUT | output | Output pin of comparator 1, an open-drain output with absolute maximum output current of 20 mA that can be wired-AND with other open-collector outputs. |
| 2 | 1IN- | input | Negative (inverting) input of comparator 1; the common-mode range upper limit is Vcc-1.5 V and input voltages must not go below -0.3 V. |
| 3 | 1IN+ | input | Positive (non-inverting) input of comparator 1; input pin voltage range is -0.3 V to 36 V. |
| 4 | GND | power_in | Ground reference pin; all voltages are referenced to network ground. |
| 5 | 2IN+ | input | Positive (non-inverting) input of comparator 2; input pin voltage range is -0.3 V to 36 V. |
| 6 | 2IN- | input | Negative (inverting) input of comparator 2; the common-mode range upper limit is Vcc-1.5 V and input voltages must not go below -0.3 V. |
| 7 | 2OUT | output | Output pin of comparator 2, an open-drain output with absolute maximum output current of 20 mA that can be wired-AND with other open-collector outputs. |
| 8 | VCC | power_in | Supply pin; the recommended Vcc range for non-V devices such as XD393 is 2 V to 30 V. |
