H11L1M

The H11L1M is a high-speed optocoupler with a logic output. It consists of an infrared emitting diode (LED) on the input side and a photodetector on the output side. The photodetector typically includes a photodiode and a high-gain transistor, providing electrical isolation between the input and output while allowing signal transmission.

Key Features:

• High-Speed Operation: Capable of high-speed signal transmission, making it suitable for digital applications.
• Logic Output: The output is compatible with TTL (Transistor-Transistor Logic) and can directly interface with various digital circuits.
• Isolation Voltage: Provides high isolation voltage (usually around 5000 Vrms) between the input and output, ensuring robust electrical isolation.
• Low Input Current: Requires low LED drive current, enhancing efficiency.
• Wide Operating Temperature Range: Suitable for use in a variety of environmental conditions.
• Compact Package: Typically available in an 8-pin DIP (Dual In-line Package) or surface-mount package, making it easy to integrate into different PCB designs.

Applications:

• Microprocessor Systems: Used to interface microcontrollers or microprocessors with other components while maintaining electrical isolation.
• Switching Power Supplies: Provides isolation and signal transmission in switching power supplies.
• Data Communication: Suitable for high-speed data communication applications that require electrical isolation.
• Industrial Automation: Used in industrial control systems to isolate control signals from high-voltage circuits.
• Telecommunications: Employed in telecommunications equipment for isolating and transmitting signals.
