Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANODE 1 | input | Anode of the channel 1 AlGaAs input LED; the datasheet specifies forward input current IF(ON) from 40 µA to 5000 µA and a reverse input voltage limit of 2.5 V. |
| 2 | CATHODE 1 | passive | Cathode of the channel 1 input LED; the datasheet limits the reverse input voltage to 2.5 V. |
| 3 | CATHODE 2 | passive | Cathode of the channel 2 input LED; the datasheet limits the reverse input voltage to 2.5 V. |
| 4 | ANODE 2 | input | Anode of the channel 2 AlGaAs input LED; the datasheet specifies forward input current IF(ON) from 40 µA to 5000 µA and a reverse input voltage limit of 2.5 V. |
| 5 | GND | power_in | Ground reference for the detector and output stages; a 0.1-µF bypass capacitor should be connected between pins 8 and 5 as close to the device as possible. |
| 6 | VO2 | output | Open-collector output of channel 2 (TTL and CMOS compatible); the output voltage is limited to −0.5 V to 18 V and the output current to 60 mA per channel. |
| 7 | VO1 | output | Open-collector output of channel 1 (TTL and CMOS compatible); the output voltage is limited to −0.5 V to 18 V and the output current to 60 mA per channel. |
| 8 | VCC | power_in | Supply voltage for the detector stage, specified from 1.6 V to 18 V (absolute maximum −0.5 V to 18 V), to be bypassed with 0.1 µF to pin 5. |
