An optoisolator, also commonly known as an optocoupler or opto-isolator, is a type of electronic component designed to convert a digital logic signal from one device into an output signal that is electrically isolated from the input. HCPL-2219#300 is a device from the family of logic output optoisolators, providing basic, high-speed optically-coupled isolation that is UL certified.

Functional Description

HCPL-2219#300 is a phototransistor output optocoupler designed for digital logic isolator applications. This device features a latching configuration which allows it to control an AC power supply, while providing high current, low peak voltage, and low RON low power consumption. It is suitable for applications requiring high efficiency, extended environment performance, lower operating temperature range, and high noise immunity.

Working Principle

The HCPL-2219#300 optoisolator works on the principle of optocoupling. An input signal is converted to light received by a phototransistor and emitted from an infrared LED. When the light passes through the optocoupler, it is converted back into electrical signal and the output signal is isolated from the input. The design of the device features an inbuilt ARINC 801 connector which facilitates the connection of the optocoupler to an external system. The internal, high-speed circuitry boosts the overall speed of the device and provides high immunity to noise, EMC, and other environmental factors.
