FOD270L - Single Channel Optocoupler

Download the FOD270L datasheet PDF. This datasheet also covers the FOD070L variant, as both devices belong to the same single channel optocoupler family and are provided as variant models within a single manufacturer datasheet.

General Description

The FOD070L, FOD270L and FOD073L optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector.

These devices are specified to operate at a 3.3V supply voltage.

LVTTL/LVCMOS COMPATIBLE LOW INPUT CURRENT HIGH GAIN SPLIT DARLINGTON OPTOCOUPLERS SINGLE CHANNEL: DUAL CHANNEL: DESCRIPTION The FOD070L, FOD270L and FOD073L optocouplers consist of an AlGaAs LED optically coupled to a high gain split darlington photodetector. These devices are specified to operate at a 3.3V supply voltage. The split darlington configuration separating the input photodiode and the first stage gain from the output transistor permits lower output saturation voltage and higher speed operation than possible with conventional darlington phototransistor optocoupler. In the dual channel device FOD073L, an integrated emitter – base resistor provides superior stability over temperature. The combination of a very low input current of 0.
