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.
