Overview
The CNY74-4H is a quad-channel optoisolator manufactured by Vishay Semiconductor Opto Division. It features four independent channels, each consisting of an aluminum gallium arsenide infrared-emitting diode optically coupled to a silicon NPN phototransistor. The device is housed in a 16-pin PDIP package and provides a high isolation voltage of 5300Vrms. Key electrical parameters include a maximum forward current of 60 mA, a collector-emitter saturation voltage of 400 mV, and a collector-emitter voltage rating of 70 V. The typical forward voltage is 1.25 V.
Feature Summary
- Quad-channel configuration with four independent galvanic isolation paths
- High insulation voltage capability of 5300Vrms for robust signal separation
- Integration of GaAlAs infrared LED with silicon NPN phototransistor
Applications
- Galvanic isolation in power supply circuits
- Signal isolation in industrial control systems
- Microprocessor system interfacing
Procurement Notes
Verify the specific suffix (e.g., -LB) against the datasheet to ensure compliance with lead-free and RoHS requirements. Confirm the package type matches the required 16-pin DIP footprint. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure the isolation voltage rating meets the safety standards of the target application environment.
Selection Notes
Select this component when multiple isolated channels are required within a single package to reduce board space. Consider the 5300Vrms isolation rating for applications demanding high dielectric strength. Evaluate the 60 mA forward current limit against the driving circuit capabilities. Compare propagation delays if high-speed switching is necessary, as this is a general-purpose transistor output device.
Part Context
The CNY74-4H belongs to the CNY74 series of quad-channel optocouplers from Vishay. It shares architectural similarities with the CNY74-2H but offers double the channel count. This series is designed for general-purpose isolation tasks where compactness and high isolation voltage are prioritized over ultra-high speed performance.
Replacement Considerations
Direct substitutes may include other quad-channel optocouplers with similar 5300Vrms isolation and 16-pin DIP packages. Verify pinout compatibility and electrical ratings such as CTR and isolation voltage before substitution.
