Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. |
| 2 | ANODE | input | LED anode; input forward current is rated 25 mA max average, with VF 1.4 V typ to 1.7 V at IF=16 mA. |
| 3 | CATHODE | input | LED cathode; reverse input voltage is limited to 5 V. |
| 4 | NC | unconnected | No internal connection. |
| 5 | GND | power_in | Ground reference of the output detector; a 0.1 µF bypass capacitor must be connected between pin 8 and pin 5. |
| 6 | VO | output | Open-collector output of the phototransistor, low when the LED is on and high when off; output voltage rated 20 V max and collector current 8 mA max. |
| 7 | VB | power_in | Base connection of the output transistor (photodiode bias node) that improves speed. |
| 8 | VCC | power_in | Detector supply voltage, rated 15 V max, requiring a 0.1 µF or larger bypass capacitor to pin 5. |
