DESCRIPTION

The IL/ILD755 are bidirectional input optically cou­pled isolators. They consist of two Gallium Ars­enide infrared emitting diodes coupled to a silicon
NPN photodarlington per channel.

The IL755 are single channel Darlington optocou­plers. The ILD755 has two isolated channels in a
single DIP package.

They are designed for applications requiring detec­tion or monitoring of AC
