Description

The CNY74-4 consists of four independent optocoupler channels, each including an LED and a phototransistor. When the LEDs are forward biased, they emit infrared light which is detected by the corresponding phototransistors. This design allows for the isolation and transmission of signals across an electrical barrier for each channel independently, while maintaining high isolation between input and output.

Features

  • Four Channels: Contains four optocoupler channels in a single package, allowing for isolation of multiple signals at once.
  • High Electrical Isolation: Provides isolation voltage up to 5000 VRMS between input and output, ensuring protection from high voltage and noise.
  • Compact DIP-14 Package: Housed in a 14-pin Dual Inline Package (DIP-14), which facilitates integration into circuit boards and saves space.
  • High Current Transfer Ratio (CTR): Ensures efficient signal transmission with high reliability.
  • Low Input Current Requirement: Operates effectively with low LED input current, contributing to energy efficiency.
  • TTL and CMOS Compatible: Can interface with TTL and CMOS logic levels, making it versatile for digital applications.
  • Reliable Performance: Known for stable performance and durability across a wide range of operating conditions.

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.
  • Current Transfer Ratio (CTR): Typically 100% to 200% at IF = 10mA, VCE = 10V (for each channel).
  • Collector-Emitter Voltage (VCEO): Maximum 70V.
  • Collector Current (IC): Maximum 50mA per channel.
  • Collector-Emitter Saturation Voltage (VCE(sat)): Maximum 0.3V at IC = 2mA, IF = 10mA.
  • Response Time:
    • Rise Time (tr): Typically 5µs.
    • Fall Time (tf): Typically 5µs.
  • Operating Temperature Range: -55°C to +100°C.

Applications

  • Multi-Channel Signal Isolation: Ideal for applications requiring the isolation of multiple signals simultaneously, such as in industrial control systems.
  • Data Communication: Useful for isolating and protecting multiple communication lines or data channels.
  • Power Supply Feedback: Commonly used in switch-mode power supplies (SMPS) to isolate multiple feedback signals.
  • Microcontroller I/O: Provides isolation for multiple microcontroller I/O lines or digital inputs/outputs.
  • Automation Systems: Suitable for industrial automation systems where multiple signals need to be isolated from high voltage or noisy environments.
