6N137-500E-JSM from JSMSEMI, 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 | NC | unconnected | No connection. |
| 2 | ANODE | input | LED anode input; recommended input forward current IF is 7.5 mA min to 15 mA max, absolute maximum 20 mA. |
| 3 | CATHODE | input | LED cathode input; input reverse voltage must not exceed 5 V. |
| 4 | NC | unconnected | No connection. |
| 5 | GND | power_in | Ground for the output detector; a 0.1 µF bypass capacitor is recommended between pins 8 and 5 with lead length under 10 mm. |
| 6 | VO | output | Open-collector output, low when the LED is on and enabled; absolute maximum 7 V and 50 mA, with pull-up RL of 330 Ω to 4 kΩ recommended. |
| 7 | VE | input | Enable input: high level 2.0 V to VCC and low level 0 to 0.8 V; absolute maximum VCC + 0.5 V and 5 mA, and the output is low only when the LED is on and VE is high or not connected. |
| 8 | VCC | power_in | Supply voltage, recommended 4.5 V to 5.5 V, absolute maximum 7 V for 1 minute. |
