DESCRIPTION
The 66311 high voltage isolator consisting of an 850 nm LED optically coupled to a radiation tolerant phototransistor. This
configuration has proven to be highly tolerant to both proton and total dose radiation. The isolator is built with hermetic
components internally optically coupled and encased in a high temperature outer PPS plastic housing.
