Introduction or Description

The FOD814 consists of two gallium arsenide infrared emitting

diodes, connected in inverse parallel, driving a silicon phototransistor

output in a 4−pin dual in−line package. The FOD817 Series consists of

a gallium arsenide infrared emitting diode driving a silicon

phototransistor in a 4−pin dual in−line package.
