6N137 from onsemi, in a PDIP-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 | N/C | no_connect | No connection. |
| 2 | + | passive | Input LED anode (+ side of VF). |
| 3 | - | passive | Input LED cathode (− side of VF). |
| 4 | N/C | no_connect | No connection. |
| 5 | GND | power_in | Output-side ground. A 0.1 µF bypass capacitor must be connected between pins 8 and 5 (Note 1). |
| 6 | VO | output | Logic gate output (open collector). |
| 7 | VE | input | Enable input (not to exceed VCC by more than 500 mV). |
| 8 | VCC | power_in | Output-side supply, 4.5 to 5.5 V operating (7.0 V max). |
