IL255 - Vishay

IL255 Optocoupler

The IL255 is a bidirectional input optically coupled isolator consisting of two high current GaAs infrared LEDs coupled to a silicon NPN phototransistor. The IL255 has a minimum CTR of 20 %. This optocoupler is ideal for applications requiring AC signal detection and monitoring. AGENCY APPROVALS • UL1577, file no. E52744 system code H, double protection • c.
