Broadcom AVAGO · Logic Output Optoisolators · SOP-8
HCPL-0453-500E 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 | Labeled NC (no connection) on the pin diagram; the datasheet states no function or limit for this pin. |
| 2 | ANODE | input | LED anode input; average forward input current is 25 mA maximum and peak forward input current is 50 mA maximum for SO-8 (50% duty cycle, 1 ms pulse width). |
| 3 | CATHODE | input | LED cathode input; it is the return for the LED forward current, with the same 25 mA average and 50 mA peak forward current limits as pin 2. |
| 4 | NC | unconnected | Labeled NC (no connection) on the pin diagram; the datasheet states no function or limit for this pin. |
| 5 | GND | power_in | Ground reference for the output and supply; the datasheet requires a 0.1 µF bypass capacitor between pins 5 and 8. |
| 6 | Vo | output | Open-collector output referenced to pin 5, rated -0.5 V to 20 V, with average output current limited to 8 mA and peak output current to 16 mA. |
| 7 | NC | unconnected | Not connected on the SO-8 (HCPL-0452/0453) part; the base-current and emitter-base ratings apply only to other device types, which the datasheet excludes for 4502/3 and 0452/3. |
| 8 | VCC | power_in | Supply voltage referenced to pin 5, rated -0.5 V to 30 V, with a 0.1 µF bypass capacitor to pin 5 recommended. |
