CYHCPL2531 from OCIC, in a DIP-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 | A1 | passive | Anode of input LED 1 (+); forward current IF(avg) max 25 mA, reverse voltage VR max 5 V. |
| 2 | K1 | passive | Cathode of input LED 1 (-); forward current IF(avg) max 25 mA, reverse voltage VR max 5 V. |
| 3 | K2 | passive | Cathode of input LED 2 (-); forward current IF(avg) max 25 mA, reverse voltage VR max 5 V. |
| 4 | A2 | passive | Anode of input LED 2 (+); forward current IF(avg) max 25 mA, reverse voltage VR max 5 V. |
| 5 | GND | power_in | Common ground for the output side of both channels. |
| 6 | VO2 | output | Open-collector transistor output of channel 2, with output voltage rated -0.5 to 20 V and average output current max 8 mA. |
| 7 | VO1 | output | Open-collector transistor output of channel 1, with output voltage rated -0.5 to 20 V and average output current max 8 mA. |
| 8 | VCC | power_in | Positive supply for the output side of both channels, with absolute maximum supply voltage of -0.5 to 30 V. |
