Description

The H11L1 consists of an infrared light-emitting diode (LED) on the input side and a Schmitt Trigger output transistor on the output side. When the LED is forward biased, it emits infrared light that is detected by the Schmitt Trigger transistor. This results in a clean, digital output with defined thresholds, ensuring that the signal is accurately transmitted and not affected by noise or signal degradation.

Features

  • Schmitt Trigger Output: Provides a digital output with a well-defined switching threshold, offering noise immunity and clean signal transitions.
  • Electrical Isolation: Offers isolation between input and output, typically up to 5000 VRMS, protecting sensitive circuits from high voltage and electrical noise.
  • Compact DIP-6 Package: The 6-pin DIP package is convenient for mounting on circuit boards and integrates easily into various designs.
  • High Noise Immunity: The Schmitt Trigger circuit ensures reliable operation even in noisy environments, reducing false triggering.
  • Low Input Current Requirement: Operates effectively with a low LED input current, enhancing energy efficiency.
  • TTL and CMOS Compatible: The output is compatible with TTL and CMOS logic levels, making it versatile for digital applications.

Specifications

  • Input LED Forward Voltage: Typically 1.2V (maximum 1.4V) at 20mA forward current.
  • Input LED Reverse Voltage: Maximum 6V.
  • Isolation Voltage: 5000 VRMS.
  • Output Collector-Emitter Voltage (VCEO): Maximum 70V.
  • Output Collector Current (IC): Maximum 50mA.
  • Current Transfer Ratio (CTR): Typically 50% to 200% at IF = 10mA, VCE = 5V (varies with conditions).
  • Output Saturation Voltage (VCE(sat)): Maximum 0.3V at IC = 10mA, IF = 10mA.
  • Response Time:
    • Rise Time (tr): Typically 3µs.
    • Fall Time (tf): Typically 5µs.
  • Operating Temperature Range: -55°C to +100°C.

Applications

  • Signal Conditioning: Provides clean digital signals with defined thresholds, making it suitable for applications requiring precise signal processing.
  • Microcontroller Interfacing: Used to interface microcontrollers with high-voltage or noisy signals, ensuring reliable operation and signal integrity.
  • Switching Power Supplies: Commonly used in feedback circuits of switch-mode power supplies (SMPS) for accurate signal isolation and conditioning.
  • Industrial Automation: Ideal for control systems where noise immunity and reliable signal transmission are essential.
  • Data Communication: Provides robust signal transmission in data communication interfaces, protecting against noise and interference.
