HCPL-4503-500E

Broadcom Limited · Transistor, Photovoltaic Output Optoisolators · DIP-8

HCPL-4503-500E from Broadcom Limited, 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 No internal connection on this package; leave unconnected.
2 ANODE input LED anode; the LED reverse input voltage (pin 3-2) is limited to 5 V and the average forward input current to 25 mA.
3 CATHODE input LED cathode; the reverse LED input voltage (pin 3-2) is limited to 5 V.
4 NC unconnected No internal connection on this package; leave unconnected.
5 GND power_in Ground and reference for the supply (pin 8-5, max 30 V) and output (pin 6-5, max 20 V); a 0.1 µF bypass capacitor should be connected between pins 5 and 8.
6 VO output Open-collector output, rated 8 mA average and 16 mA peak output current, with output voltage limited to -0.5 V to 20 V referenced to pin 5.
7 NC unconnected No connection on the HCPL-4502/4503 (the base-current rating applies only to other devices in the family).
8 VCC power_in Supply voltage, rated -0.5 V to 30 V referenced to pin 5; a 0.1 µF bypass capacitor should be connected between pins 5 and 8.
