DESCRIPTION
The ILD255 is a bidirectional input optically coupled isolator consisting of two high current Gallium Arsenide infrared LEDs coupled to a silicon NPN phototransistor per channel. The ILD255 has a minimum CTR of 50%
These optocouplers are ideal for applications requiring AC signal detection and monitoring.
