Dual Optocoupler with NPN Output – 8-Pin DIP

High-Reliability Dual Optocoupler – NTE3220

The NTE3220 dual optocoupler is designed for demanding applications requiring isolated signal transfer and high noise immunity. Housed in a compact 8-pin DIP package, this optoisolator features two independent NPN phototransistor output channels, allowing for reliable and robust electrical isolation between control and signal circuits.

Technical Specifications

• Configuration: Dual channel optocoupler
• Package: 8-Pin DIP
• Output Type: NPN phototransistor
• Isolation Voltage: Typically rated for high isolation between input and output
• Channels: Two completely isolated optocouplers in one package

Key Features and Benefits

• Efficient optical isolation for minimizing ground loops and transient noise.
• Dual independent optoisolators offer space-saving integration on PCBs.
• NPN output provides straightforward interfacing with digital logic circuits or microcontrollers.
• Suitable for switching, signal isolation, feedback circuits, or sensing applications.

Typical Applications

• Power supply feedback circuitry
