HCNW4506-300E

Broadcom Limited · Logic Output Optoisolators · DIP-8

HCNW4506-300E 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 shown in the functional diagram.
2 ANODE input LED anode input; the output VO is HIGH when the LED is ON and LOW when it is OFF.
3 CATHODE input LED cathode input; the output VO is HIGH when the LED is ON and LOW when it is OFF.
4 NC unconnected No internal connection shown in the functional diagram.
5 GND power_in Ground (VEE) of the output detector; a 0.1-µF bypass capacitor must be connected between VCC and this pin.
6 VO output Detector output, HIGH when the LED is ON and LOW when OFF; shorting pins 6 and 7 enables the on-chip 20-kΩ pull-up resistor.
7 VL passive Connection to the on-chip 20-kΩ output pull-up resistor, enabled by shorting pins 6 and 7, eliminating an external pull-up.
8 VCC power_in Positive supply for the output detector; a 0.1-µF bypass capacitor must be connected between VCC and VEE.
