Optocoupler, Phototransistor Output (Multichannel)
CNY74-2H, CNY74-4H
Vishay Semiconductors
DESCRIPTION
The CNY74-2H, CNY74-4H is an optically coupled pair with
a GaAIAs infrared LED and a silicon NPN phototransistor.
Signal information, including a DC level, can be transmitted
by the device while maintaining a high degree of electrical
isolation between input and output.
The CNY74-2H, CNY74-4H is especially for driving
medium-speed logic, where it may be used to eliminate
troublesome ground loop and noise problems. Also it can be
used to replace relays and transformers in many digital
interface applications, as well as analog applications such as
CTR modulation.
The CNY74-2H has two isolated channels in a single DIP
package; the CNY74-4H has four isolated channels per
package.
