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 photo
transistor optocouplers by reducing the base-collector capacitan...
