FOD053L
Description
The FOD250L, FOD050L and FOD053L optocouplers
consist of an AlGaAs LED optically coupled to a high
speed photodetector transistor. These devices are speci-
fied 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
35kV/ms (typical).
