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