Isocom Components 2004 LTD H11L1 Environmental and export classification status description

of Isocom Components H11L1 The H11L1 is an optocoupler (opto-isolator) used for transmitting signals between its input and output while maintaining electrical isolation. This device typically consists of a light-emitting diode (LED) and a phototransistor. Functions - Signal Isolation: Ensures that high-voltage and low-voltage circuits are isolated from each other, providing safety and protecting components. - Signal Transmission: Transmits digital signals across the isolator via optical means, meaning that the input signal controls the output through light rather than electrical conduction. - Low Input Current: Requires a low input current to activate, making it energy-efficient. Applications - Data Communication: Used in data communication systems for isolation of digital signals. - Power Supply Isolation: Commonly found in switching power supplies to isolate the feedback signal. - Microcontroller Interfaces: Used in interfacing microcontrollers and other digital logic devices where isolation is necessary. - Signal Conditioning: Employed in instrumentation systems to prevent ground loops and other interference. Alternative Parts Some alternative optocouplers to the H11L1 include: - H11L2: Offers similar characteristics but may vary in gain and response time. - HCPL-2601: Another optocoupler with different packaging and pin configurations, suitable for different applications. Embedded Modules The H11L1 may be integrated into various embedded systems modules that require signal isolation, such as: - Arduino Shields: For projects needing isolation between components. - Raspberry Pi Interfaces: Often used to safely connect non-isolated components. - Custom PCB Designs: Implemented in designs that require optical isolation for sensitive components.
