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.
