DESCRIPTION

The IL255 is a bidirectional input optically cou- pled isolator consisting of two high current Gal- lium Arsenide infrared LEDs coupled to a silicon NPN phototransistor. The IL255 has a minimum CTR of 20% This optocoupler is ideal for applications requir- ing AC signal detection and monitoring.
