8-pin SOIC (FOD050L) or dual channel 8-pin SOIC
(FOD053L)
■ Superior CMR – CMH = 50kV/µs (typical) and
CML = 35kV/µs (typical)
■ Guaranteed performance over temperature:
0°C to 70°C
■ U.L. recognized (File # E90700)
■ VDE pending
Applications
■ Line receivers
■ Pulse transformer replacement
■ High speed logic ground isolation: LVTTL/LVCMOS
■ Wide bandwidth analog coupling
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-col-
lector capacitance of the input transistor.
An internal noise shield provides superior common
mode rejection of CMH = 50kV/ms (typical) and CML =
35kV/ms (typical).
