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.
FOD814: 20–300%
FOD814A: 50–150%
FOD817: 50–600%
FOD817A: 80–160%
FOD817B: 130–260%
FOD817C: 200–400%
FOD817D: 300–600%

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
