# HCPL-0201-500E

**Broadcom AVAGO** · Logic Output Optoisolators · SO-8

HCPL-0201-500E 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 | NC | unconnected | No internal connection on the SO-8 (HCPL-0201/11 family) pinout; leave unconnected. |
| 2 | ANODE | input | LED anode input; the LED is driven with an on-state forward current of 1.6 mA to 5 mA (1.8 mA minimum for HCPL-223X) and must be held at VF(OFF) ≤ 0.8 V for logic low. |
| 3 | CATHODE | input | LED cathode; reverse input voltage is limited to 5 V and average forward input current to 10 mA. |
| 4 | NC | unconnected | No internal connection on the SO-8 pinout; leave unconnected. |
| 5 | GND | power_in | Detector ground reference; a 0.1 µF bypass capacitor must be connected between pins 5 and 8. |
| 6 | VO | output | Totem-pole logic output (no pull-up required) with output voltage limited to -0.5 V to 20 V and average output current limited to 25 mA. |
| 7 | NC | unconnected | No connection on the SO-8 pinout; the datasheet labels the internal SHIELD near this pin but does not assign it an external function, so leave unconnected. |
| 8 | VCC | power_in | Supply voltage: recommended 4.5 V to 20 V (absolute maximum 0 to 20 V), with a 0.1 µF bypass capacitor to pin 5. |
