# HCPL-0211-500E

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

HCPL-0211-500E 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 (NC) on the SO-8 HCPL-0201/11 pin assignment; leave unconnected. |
| 2 | ANODE | input | LED anode; drive with forward input current IF(ON) of 1.6 mA to 5 mA (1.8 mA minimum for HCPL-223X) and keep VF(OFF) at or below 0.8 V for logic low. |
| 3 | CATHODE | input | LED cathode of the input photodiode; reverse input voltage rating is 5 V maximum. |
| 4 | NC | unconnected | No internal connection (NC) on the SO-8 HCPL-0201/11 pin assignment; leave unconnected. |
| 5 | GND | power_in | Ground reference for the detector side; a 0.1 μF bypass capacitor is required between pins 5 and 8. |
| 6 | NC | unconnected | No internal connection (NC) on the SO-8 HCPL-0201/11 pin assignment; leave unconnected. |
| 7 | VO | output | Totem-pole logic output (no pull-up resistor required); average output current is limited to 25 mA maximum and output voltage ranges from -0.5 V to 20 V. |
| 8 | VCC | power_in | Detector supply voltage with a 4.5 V to 20 V recommended operating range (absolute maximum 0 to 20 V); bypass with 0.1 μF to pin 5. |
