HCPL-050L-500E

Broadcom AVAGO · Logic Output Optoisolators · SOP-8

HCPL-050L-500E from Broadcom AVAGO, in a SOP-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 No connection; the functional diagram labels this pin NC, so it should be left unconnected.
2 ANODE input LED anode input; the reverse LED input voltage (pin 3-2) is rated at 5 V maximum, and forward input current IF(ON) is 16 to 20 mA in the recommended operating conditions.
3 CATHODE input LED cathode input; the reverse LED input voltage (pin 3-2) is rated at 5 V maximum and the input forward voltage is 0 to 0.8 V when off.
4 NC unconnected No connection; the functional diagram labels this pin NC, so it should be left unconnected.
5 GND power_in Ground reference for the output and supply; a 0.1 µF bypass capacitor should be connected between pins 5 and 8.
6 VO output Open-collector output; average output current (pin 6) is limited to 8 mA and output voltage (pin 6-5) to -0.5 V to 7 V.
7 VB power_in Photodiode bias connection, separate from the output collector; base current IB is limited to 5 mA maximum.
8 VCC power_in Supply voltage; recommended range is 2.7 V to 7.0 V (absolute maximum -0.5 V to 7 V, pin 8-5), with a 0.1 µF bypass to pin 5.
