DESCRIPTION
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 CM
