03/02/2011
Features:
Hermetically Sealed
Designed to be proton radiation tolerant
High Current Transfer Ratio - 200% minimum
1000 Vdc electrical input to output isolation
Applications:
Ground loop isolation

DESCRIPTION
The 66212 optocoupler consists of an 850 nm GaAIAs LED optically coupled to a phototransistor detector all mounted in a
hermetic 4 pin LCC package. This configuration has proven to be highly tolerant to proton radiation. The 850 nm LED has
proven to be more tolerant of operating temperatures over 100°C than the more commonly used 660 nm LED.
