DESCRIPTION
The ILD255 is a bidirectional input optically cou-
pled 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.
