AT075L-CuH-S from AOTE, in a SOP-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 | LED anode of channel 1; absolute maximum average forward input current is 20 mA and recommended on-state forward current IF(ON) is 9 to 18 mA. |
| 2 | Cathode 1 | passive | LED cathode of channel 1, returning the forward input current (20 mA maximum average) from Anode 1. |
| 3 | Cathode 2 | passive | LED cathode of channel 2, returning the forward input current (20 mA maximum average) from Anode 2. |
| 4 | Anode 2 | passive | LED anode of channel 2; absolute maximum average forward input current is 20 mA and recommended on-state forward current IF(ON) is 9 to 18 mA. |
| 5 | GND | power_in | Output-side ground reference for the receiver, isolated from the input LEDs (isolation voltage 3750 Vrms). |
| 6 | VO 2 | output | Channel 2 logic output; output current is limited to 10 mA maximum and output voltage to VDD+0.5 V maximum. |
| 7 | VO 1 | output | Channel 1 logic output; output current is limited to 10 mA maximum and output voltage to VDD+0.5 V maximum. |
| 8 | VCC | power_in | Output-side supply; recommended 4.5 to 5.5 V or 3 to 3.6 V, absolute maximum 6 V. |
