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 ILD74, ILQ74 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 ILD74 has two isolated channels in a single DIP package; the ILQ74 has four isolated channels per package. FEATURES ILD74, ILQ74 TTL compatible Transfer ratio, 35 % typical Coupling capacitance, 0.5 pF Single, dual, and quad channel Industry standard DIP packages Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 AGENCY APPROVALS UL 1577 cUL DIN EN 60747-5-5 (VDE 0884-5), available with option 1 CQC FIMKO LINKS TO ADDITIONAL RESOURCES Related Documents Rev. 2.0, 11-Jan-2024 1 Document Number: 83640 For technical questions, contact: optocoupleranswers@vishay.com THIS DOCUMENT IS SUBJECT TO CHANG...
