6N137M from UMW, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |
| 2 | VF+ (Anode) | input | LED anode of the input emitter. Drive with forward current IF (typ. 6.3-15 mA for high-level operation, absolute max IF = 50 mA). Typical VF = 1.4 V at IF = 10 mA. |
| 3 | VF- (Cathode) | input | LED cathode of the input emitter. Return path for LED forward current. Absolute maximum reverse input voltage VR = 5 V. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |
| 5 | GND | power_in | Output-side ground reference for the detector logic gate. Bypass VCC to this pin with a local decoupling capacitor. |
| 6 | VO | output | Open-collector logic gate output. Requires an external pull-up resistor to VCC. Absolute max VO = 7 V, IO = 50 mA; guaranteed sink of 13 mA (fan-out of 8 TTL loads). Supports wired-OR with other open-collector outputs. |
| 7 | VE | input | Strobe/Enable input for the output logic gate. VEH >= 2 V enables output (data passes); VEL <= 0.8 V forces output high. Must not exceed VCC by more than 500 mV (abs max 5.5 V). |
| 8 | VCC | power_in | Output-side positive supply. Recommended 4.5-5.5 V; absolute max 7 V. Decouple to GND (pin 5) with a local ceramic capacitor near the device. |
