Features:
 Current Transfer Ratio-200% typical
 1 kVdc electrical input to output isolation
 Base lead provided for conventional transistor
biasing
 Proton radiation tolerant
Applications:
 Eliminate ground loops
 Level shifting
 Line receiver

DESCRIPTION
The 66227 Optocoupler consists of an 850nm GaAIAs LED optically coupled to a phototransistor mounted in a hermetic TO-5
package. Test studies have shown this LED to be even more radiation tolerant than the 660nm LED typically used in radiation
tolerant applications. Available in commercial or screened levels.
