DESCRIPTION
The 66225 optocoupler consists of an 850 nm GaAIAs LED optically coupled to a photodiode detector and a 2N2222
transistor all mounted in a hermetic TO72 package. This configuration has proven to be highly tolerant to both proton and
total dose radiation. The 850 nm LED has proven to be more tolerant of operating temperatures over 100°C than the more
commonly used 660nm LED.
