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).

Notes:
2. The 1.9kload represents 1 TTL unit load of 1.6mA and 5.6kpull-up resistor.
3. The 4.1kload represents 1 LSTTL unit load of 0.36mA and 6.1kpull-up resistor.
4. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading
edge of the common mode pulse signal VCM, to assure that the output will remain in a logic high state
(i.e., VO > 2.0V). Common mode transient immunity in logic low level is the maximum tolerable (negative)
dVcm/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a
logic low state (i.e., VO < 0.8V).
5. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are
shorted together.
