6N138M from UMW, 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 | NC | unconnected | No connection; pin 1 is drawn with no internal connection and no label in the pinning diagram. |
| 2 | Anode | passive | Anode of the AlGaAs infrared emitting diode input (absolute maximum forward current 25 mA, reverse voltage 5 V). |
| 3 | Cathode | passive | Cathode of the infrared emitting diode input (absolute maximum forward current 25 mA, reverse voltage 5 V). |
| 4 | NC | unconnected | No connection; pin 4 is drawn with no internal connection and no label in the pinning diagram. |
| 5 | Emitter | passive | Emitter of the output darlington phototransistor, which serves as the output-side ground return. |
| 6 | Collector | output | Collector of the output darlington transistor, the open-collector output (VO absolute maximum -0.5 to 18 V, IO maximum 60 mA). |
| 7 | VB | power_in | Base connection of the output phototransistor (VB), used for an optional base-emitter resistor; the datasheet states no other limits for it. |
| 8 | VCC | power_in | Output-side supply voltage, absolute maximum -0.5 to 18 V. |
