HCPL-0531-500E

Broadcom AVAGO · Logic Output Optoisolators · SO-8

HCPL-0531-500E 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 input Anode of the channel 1 input LED; the datasheet limits average forward current to 25 mA per channel, peak forward current to 50 mA (50% duty cycle, 1 ms pulse), and reverse LED input voltage to 5 V.
2 CATHODE 1 passive Cathode of the channel 1 input LED; the input LED reverse voltage is rated at 5 V maximum per channel.
3 CATHODE 2 passive Cathode of the channel 2 input LED; the input LED reverse voltage is rated at 5 V maximum per channel.
4 ANODE 2 input Anode of the channel 2 input LED; the datasheet limits average forward current to 25 mA per channel, peak forward current to 50 mA (50% duty cycle, 1 ms pulse), and reverse LED input voltage to 5 V.
5 GND power_in Common ground and reference for both output transistors and the supply; a 0.1 µF bypass capacitor between pins 5 and 8 is recommended.
6 VO2 output Open-collector output of channel 2; output voltage is rated -0.5 V to 20 V (pin 6 to 5), average output current 8 mA and peak output current 16 mA per channel.
7 VO1 output Open-collector output of channel 1; output voltage is rated -0.5 V to 20 V (pin 7 to 5), average output current 8 mA and peak output current 16 mA per channel.
8 VCC power_in Supply pin for the photodiode bias and output stages; supply voltage is rated -0.5 V to 30 V (pin 8 to 5), with a 0.1 µF bypass to pin 5 recommended.
