**AOTE** · Logic Output Optoisolators · DIP-6

ATH11L3-CuH-D from AOTE, in a DIP-6. 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 | passive | LED anode of the input emitter; forward current IF max 60 mA, turn-on threshold for ATH11L3 is 5 mA min with recommended IF(on) 5 to 15 mA. |
| 2 | Cathode | passive | LED cathode of the input emitter; reverse voltage VR max 6 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | VO | output | Open-collector output pin; V45 allowed range 0 to 16 V, output current IO max 50 mA, VOL max 0.4 V. |
| 5 | GND | power_in | Output-side ground reference of the detector IC. |
| 6 | VCC | power_in | Output-side supply voltage; V65 allowed range 3 to 16 V, recommended 3 to 15 V. |
