General Description
The FOD0708 and FOD0738 optocouplers consist of an
AlGaAs LED optically coupled to a high speed trans-
impedance amplifier and voltage comparator. These
optocouplers utilize the latest CMOS IC technology to
achieve outstanding performance with very low power
consumption. The devices are housed in a compact
8-pin SOIC package for optimum mounting density.
