HCPL-070A-500E from Broadcom AVAGO, in a SOIC-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 | NC | unconnected | Labeled NC (no connection) in the datasheet pinout; the datasheet gives no function for this pin. |
| 2 | ANODE | input | AlGaAs input LED anode, specified for forward input current IF(ON) of 40 µA to 5000 µA and forward input voltage VF(OFF) of 0 V to 0.8 V in the off state. |
| 3 | CATHODE | input | AlGaAs input LED cathode; the input reverse voltage VR is limited to a maximum of 2.5 V. |
| 4 | NC | unconnected | Labeled NC (no connection) in the datasheet pinout; the datasheet gives no function for this pin. |
| 5 | GND | power_in | Ground reference for the detector IC and output stage; a 0.1 µF bypass capacitor between pins 8 and 5 is recommended. |
| 6 | VO | output | Open-collector split-Darlington output, rated for an output voltage of -0.5 V to 18 V and an output current of 60 mA maximum per channel. |
| 7 | VB | power_in | Output transistor base connection, which is left open for the single-channel product (note 9); the output transistor base current is limited to 5 mA maximum. |
| 8 | VCC | power_in | Supply pin for the detector IC, with a recommended operating range of 1.6 V to 18 V and an absolute maximum of 18 V; a 0.1 µF bypass to pin 5 is recommended. |
