Vishay ILQ1 Phototransistor Optocoupler

The ILQ1 is a 4-channel, 16-pin phototransistor optocoupler designed for medium-speed digital logic applications. It employs GaAs infrared LEDs and silicon NPN phototransistors to provide electrical isolation of up to 5300Vrms. This optocoupler effectively eliminates ground loop and noise issues, making it suitable for use in digital interfaces, replacing relays and transformers for signal isolation and transmission of DC levels. Common applications include communications, networking, and signal processing. Note that increased market demand may lead to extended lead times and fluctuating delivery dates; the product is not eligible for discounts.
