HCPL-0661-500E from Broadcom AVAGO, in a SO-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 | ANODE 1 | passive | Anode of LED 1 (channel 1 input); the datasheet recommends about 5 mA input on-current. |
| 2 | CATHODE 1 | passive | Cathode of LED 1 (channel 1 input). |
| 3 | CATHODE 2 | passive | Cathode of LED 2 (channel 2 input). |
| 4 | ANODE 2 | passive | Anode of LED 2 (channel 2 input). |
| 5 | GND | power_in | Ground for the output side; a 0.1 µF bypass capacitor must be connected as close as possible between pins 5 and 8. |
| 6 | VO2 | output | Channel 2 open-collector Schottky-clamped output, low when LED 2 is on. |
| 7 | VO1 | output | Channel 1 open-collector Schottky-clamped output, low when LED 1 is on. |
| 8 | VCC | power_in | Supply voltage for the output detector; a 0.1 µF bypass capacitor must be connected as close as possible between pins 5 and 8. |
