Description
The FODM121 series, FODM124, 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 2.54 mm. The
FODM2705 consists of two gallium arsenide infrared emitting diodes
connected in inverse parallel for AC operation.

(Note 2)
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
2. Steady state isolation voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1 and 2 are common, and pins 3 and
4 are common.
