LM2903NS08ARBE from GR, in a SOP-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 | OUT1 | output | Open-drain output of comparator 1, which can be wired-AND with other open-collector outputs. |
| 2 | IN1- | input | Negative (inverting) input of comparator 1; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow. |
| 3 | IN1+ | input | Positive (non-inverting) input of comparator 1; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow. |
| 4 | GND | power_in | Ground pin; all voltage values except differential voltages are referenced to network ground. |
| 5 | IN2+ | input | Positive (non-inverting) input of comparator 2; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow. |
| 6 | IN2- | input | Negative (inverting) input of comparator 2; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow. |
| 7 | OUT2 | output | Open-drain output of comparator 2, which can be wired-AND with other open-collector outputs. |
| 8 | VCC | power_in | Single supply pin; the datasheet specifies a single supply voltage of 2 V to 32 V (dual supply ±16 V also possible). |
