Transistor Output
These devices consist of a gallium arsenide infrared emitting diode optically
coupled to a monolithic silicon phototransistor detector, in a surface mountable,
small outline, plastic package. They are ideally suited for high density
applications, and eliminate the need for through–the–board mounting.
