Description

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.

Order Information
