DESCRIPTION
The IL755, 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 is single channel Darlington optocoupler. The
ILD755 has two isolated channels in a single DIP package.
