Description: For higher speed applications, up to 1-MHz NRZ, the Schmitt-trigger output HllL series optoisolator provides many features. The 1.6-mA drive current allows fan-in circuitry to drive the IRED, while the 5-V, 270-0 sink capability and 100ns transition times of the output add to the logic coupling flexibility.
The HllL series optoisolator is designed for applications requiring high-speed data transmission, specifically those operating at frequencies up to 1 MHz using Non-Return-to-Zero (NRZ) signaling. The device features a Schmitt-trigger output, which enhances its performance by providing clean signal transitions and improved noise immunity. This is particularly beneficial in environments where signal integrity is critical.
With a drive current of 1.6 mA, the optoisolator is capable of interfacing with fan-in circuitry, which allows multiple inputs to be combined into a single output. This capability is essential in complex systems where multiple signals need to be processed efficiently. The internal Infrared Emitting Diode (IRED) is activated by this current, enabling the optoisolator to transmit signals across an isolation barrier.
The output stage of the device is characterized by a 5-V supply voltage and a sink capability of 270 mA, which allows for robust signal handling. This feature is particularly useful in applications where the output must drive subsequent stages of logic circuits or other components that require a significant amount of current. The 100 ns transition time ensures rapid response to input changes, which is vital for maintaining high data rates and minimizing latency in communication systems.
Overall, the HllL series optoisolator is an effective solution for high-speed logic coupling, offering flexibility and reliability for various electronic applications. Its combination of Schmitt-trigger output, adequate drive current, and fast transition times make it suitable for integration into modern digital systems.For higher speed applications, up to 1-MHz NRZ, the Schmitt-trigger output HllL series optoisolator provides many features.
