ILQ1 Description

Short technical summary and product information.

The Vishay Semiconductors ILQ1 is a quad-channel optocoupler featuring a phototransistor output. It employs GaAs infrared LEDs and silicon NPN phototransistors to transmit signal information while maintaining high electrical isolation between input and output. This device is suitable for driving medium-speed logic and can help eliminate ground loop and noise issues.

 

Key electrical specifications include an isolation rated voltage of 4420 VRMS and a maximum input current of 60 mA. The current transfer ratio ranges from a minimum of 20% at 10 mA to a maximum of 300% at 10 mA. Vce saturation is a maximum of 400mV. Switching characteristics include turn-on times of 700ns and 1.4µs, and turn-off times of 1.9µs and 1.4µs.

 

Designed for through-hole mounting, the ILQ1 comes in a 16-DIP package with dimensions of 0.300 inches (7.62mm). It operates within a temperature range of -40°C to 100°C. The device is RoHS3 compliant, has an MSL of 1, and is REACH unaffected.

 

This optocoupler is ideal for applications requiring reliable signal isolation in digital interface applications, replacing relays and transformers where appropriate.
