CNY74-4H Description

Short technical summary and product information.

The Vishay CNY74-4H is a multichannel optocoupler designed for applications requiring high electrical isolation between input and output. It utilizes a GaAIAs infrared LED coupled with a silicon NPN phototransistor.

This device is particularly useful for driving medium-speed logic circuits, helping to eliminate ground loops and noise issues. It can also serve as a replacement for relays and transformers in various digital interface applications, as well as analog applications like CTR modulation.

The CNY74-4H is housed in an industry-standard 16-pin DIP package, making it suitable for through-hole mounting. Key electrical specifications include a peak reverse voltage of 3V, a forward continuous current of 60 mA, and an isolation test voltage of 5300 V RMS.

It offers a typical transfer ratio of 35% and a current transfer ratio ranging from 50% to 600%. The device also features a low coupling capacitance of 0.5 pF. Absolute maximum ratings are provided for input and output parameters to ensure safe operation.
