| 2 | Cathode 1 | passive | Cathode of channel 1 input LED, where the reverse input voltage must not exceed 5 V. |
| 3 | Cathode 2 | passive | Cathode of channel 2 input LED, where the reverse input voltage must not exceed 5 V. |
| 4 | Anode 2 | input | Anode of channel 2 input LED, with recommended forward current IF(ON) of 6 to 20 mA and absolute maximum average forward current of 25 mA. |
| 5 | GND | power_in | Output-side ground reference for the detector stages. |
| 6 | VO 2 | output | Channel 2 open-collector output, with absolute maximum output voltage of -0.5 to 20 V and output current of 8 mA. |
| 7 | VO 1 | output | Channel 1 open-collector output, with absolute maximum output voltage of -0.5 to 20 V and output current of 8 mA. |
| 8 | VCC | power_in | Output-side supply voltage with absolute maximum rating of -0.5 to 30 V and recommended range of 0.5 to 30 V. |
