HCPL-2631-000E

Broadcom AVAGO · Logic Output Optoisolators · DIP-8

HCPL-2631-000E from Broadcom AVAGO, in a DIP-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 Anode of the channel 1 input LED, driven with an input current of 5 mA for the on state.
2 CATHODE 1 passive Cathode of the channel 1 input LED.
3 CATHODE 2 passive Cathode of the channel 2 input LED.
4 ANODE 2 passive Anode of the channel 2 input LED, driven with an input current of 5 mA for the on state.
5 GND power_in Ground for the output side, with a 0.1 µF bypass capacitor connected as close as possible between pins 5 and 8.
6 VO2 output Channel 2 open-collector Schottky-clamped output, low when the LED is on and high when off.
7 VO1 output Channel 1 open-collector Schottky-clamped output, low when the LED is on and high when off.
8 VCC power_in Supply voltage for the output detector, with a 0.1 µF bypass capacitor connected as close as possible between pins 5 and 8.
