ILQ1 Description

Short technical summary and product information.

The Vishay Semiconductors ILQ1 is an optically coupled isolator featuring GaAs infrared LEDs and silicon NPN phototransistors. This quad-channel device is designed for driving medium-speed logic and provides high electrical isolation between input and output.

 

Key electrical specifications include an isolation rated voltage of 4420 VRMS and a typical Current Transfer Ratio (CTR) of 100% at an input current of 10 mA. These optocouplers are suitable for applications requiring signal isolation, such as eliminating ground loops and noise problems, and can be used in digital interface applications.

 

The ILQ1 is available in a DIP-16 package, suitable for through-hole mounting. It is designed to transmit signal information, including DC levels, while maintaining a high degree of electrical isolation.

 

This component is part of the ILQ series, which includes dual and quad channel optocouplers. The device is intended for applications where reliable signal transmission and isolation are critical.
