HCPL-070A-500E

Broadcom AVAGO · Logic Output Optoisolators · SOIC-8

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.
