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