ILQ74 Description

Short technical summary and product information.

The Vishay Dale ILQ74 is an optically coupled isolator featuring four channels, each with a GaAIAs infrared LED and a silicon NPN phototransistor. This device offers a high degree of electrical isolation, transmitting signal information while maintaining separation between input and output.

 

Key electrical characteristics include a minimum transfer ratio of 12.5% at 16mA, a maximum Vce saturation of 500mV, and a nominal current rating of 60mA. The isolation voltage is rated at 5300Vrms. It is suitable for driving medium-speed logic, eliminating ground loops and noise issues, and can replace relays and transformers in various digital and analog interface applications.

 

The ILQ74 is available in a 16-DIP package and is designed for through-hole mounting. It operates across a temperature range of -55°C to 100°C. The device is RoHS3 compliant, has an MSL of 1, and is REACH unaffected.

 

This optocoupler is TTL compatible and offers features like a typical transfer ratio of 35% and a coupling capacitance of 0.5pF.
