Description
The FODM124, FODM121 series, and FODM2701
consists of a gallium arsenide infrared emitting diode
driving a phototransistor in a compact 4-pin mini-flat
package. The lead pitch is 2.54mm. The FODM2705
consists of two gallium arsenide infrared emitting diodes
connected in inverse parallel for AC operation.

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise specified)
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.
