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.
Truth Table
LED On Off VO LOW 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 CMH = 50kV/ms (typical) and CML - 35kV/ms (typical).

Notes 1. Current Transfer Ratio is defined as a ratio of output collector current, IO, to the forward LED input current, IF, times 100%. 2. The 1.9 k load represents 1 TTL unit load of 1.6 mA and 5.6 k pull-up resistor. 3. The 4.1 k load represents 1 LSTTL unit load of 0.36 mA and 6.1k pull-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>2.0 V). 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<0.8 V). 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.
