ILQ74

Optocoupler, Phototransistor Output (Dual, Quad Channel) ILD74, ILQ74 Vishay Semiconductors DESCRIPTION The ILD74, ILQ74 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 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 • Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC
