6N137-500E from Broadcom AVAGO, 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 | NC | unconnected | No internal connection on the single-channel 6N137. |
| 2 | ANODE | passive | LED anode input; recommended high-level input current IFH is 5 to 15 mA (average forward current max 20 mA). |
| 3 | CATHODE | passive | LED cathode input; the LED is off when input current is 0 to 250 µA (or VF ≤ 0.8 V). |
| 4 | NC | unconnected | No internal connection on the single-channel 6N137. |
| 5 | GND | power_in | Output-side ground; connect the 0.1 µF bypass capacitor as close as possible between pins 5 and 8. |
| 6 | VO | output | Open-collector Schottky-clamped output with an external pull-up RL of 330 Ω to 4 kΩ; absolute max 7 V and 50 mA. |
| 7 | VE | input | Enable input: high level 2.0 V to VCC, low level 0 to 0.8 V; output is forced high when low; tie to VCC if unused for better CMR. |
| 8 | VCC | power_in | Supply voltage, recommended 4.5 to 5.5 V (absolute max 7 V for 1 minute); needs a 0.1 µF bypass capacitor to pin 5. |
