DESCRIPTION
Radiation tests performed on the 66099 optocoupler have shown that the electrical performance of the device after irradiation
is an order of magnitude better than the 4N49 optocouplers. The 66191 has the same components and layout in a 6 pin,
hermetically sealed leadless chip carrier package. Figures 1 and 2 from the 66099 data sheet illustrate the radiation
performance of the device
