HCPL-4503-000E 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 | NC | unconnected | Not internally connected; the datasheet shows this pin as NC in the functional diagram. |
| 2 | ANODE | passive | Input LED anode; the datasheet specifies IF = 16 mA for the test conditions and a maximum average forward input current of 25 mA. |
| 3 | CATHODE | passive | Input LED cathode; the reverse LED input voltage (pin 3-2) is rated at 5 V maximum for the 8-Pin DIP. |
| 4 | NC | unconnected | Not internally connected; the datasheet shows this pin as NC in the functional diagram. |
| 5 | GND | power_in | Ground reference for the output and supply; a 0.1 µF bypass capacitor must be connected between pins 5 and 8. |
| 6 | Vo | output | Open-collector output; the absolute maximum output voltage (pin 6-5) is 20 V and average output current is 8 mA maximum. |
| 7 | NC | unconnected | Not internally connected on the HCPL-4502/4503; the datasheet's base-current rating excludes these parts, so no base connection is provided. |
| 8 | VCC | power_in | Positive supply; the absolute maximum supply voltage (pin 8-5) is 30 V, with a 0.1 µF bypass capacitor recommended between pins 5 and 8. |
