DESCRIPTION
LED

V
O
LOW
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.
Off
HIGH
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 = 50kV/ms (typical) and CM - 35kV/ms (typical).

Notes
1. Current Transfer Ratio is defined as a ratio of output collector current, I , to the forward LED input current, I , times 100%.
O
F
2. The 1.9 kΩ load represents 1 TTL unit load of 1.6 mA and 5.6 kΩ pull-up resistor.
3. The 4.1 kΩ load represents 1 LSTTL unit load of 0.36 mA and 6.1kΩ pull-up resistor.
4. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV /dt on the leading edge of the
cm
common mode pulse signal V , to assure that the output will remain in a logic high state (i.e., V >2.0 V). Common mode
CM
O
transient immunity in logic low level is the maximum tolerable (negative) dV /dt on the trailing edge of the common mode
cm
pulse signal, V , to assure that the output will remain in a logic low state (i.e., V <0.8 V).
CM
O
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.
