OPTOELECTRONIC PRODUCTS
DIVISION
Features:
Applications:
• Hermetically Sealed
• Designed to be proton radiation tolerant
• High Current Transfer Ratio - 200% minimum
• 1000 Vdc electrical input to output isolation
• Ground loop isolation
• Level shifting
• Line receiver
• Switching power supplies
• Motor control
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.
