DESCRIPTION
The IL/ILD755 are bidirectional input optically cou-
pled isolators. They consist of two Gallium Ars-
enide infrared emitting diodes coupled to a silicon
NPN photodarlington per channel.
The IL755 are single channel Darlington optocou-
plers. The ILD755 has two isolated channels in a
single DIP package.
They are designed for applications requiring
detection or monitoring of AC signals.
