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.
FEATURES
• CNY74-2H, CNY74-4H TTL compatible
• Transfer ratio, 35 % typical
• Coupling capacitance, 0.5 pF
• Dual and quad channel
• Industry standard DIP packages
• Compliant to RoHS directive 2002/95/EC and
in accordance to WEEE 2002/96/EC
AGENCY APPROVALS
• UL1577, file no. E52744 system code H, double protection
• UL1577, file no. E52744, equivalent to CSA bulletin 5A

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied
at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for
extended periods of the time can adversely affect reliability.
Note

Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements.
