DESCRIPTION
IL66, ILD66, and ILQ66 are optically coupled isola-
tors employing Gallium Arsenide infrared emitters
and silicon photodarlington detectors. Switching
can be accomplished while maintaining a high
degree of isolation between driving and load cir-
cuits, with no crosstalk between channels.
