The FOD250L, FOD050L and FOD053L optocouplers consist of an AlGaAs LED optically coupled to a high speed photodetector transistor. These devices are specified for operation at a 3.3V supply voltage.
A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.
An internal noise shield provides superior common mode rejection of CMH = 50kV/ms (typical) and CML = 35kV/ms (typical).

FOD073L 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.
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 0.5 mA and a high current transfer ratio of 2000% makes this family particularly useful for input interface to MOS, CMOS, LSTTL and EIA RS232C, while output compatibility is ensured to LVCMOS as well as high fan-out LVTTL requirements.
An internal noise shield provides exceptional common mode rejection of 10 kV/s.
