Features:
Current transfer ratio: 150% typical
1000 Vdc isolation test voltage
Base lead provided for conventional transistor biasing
Low power consumption
High radiation immunity
Applications:
Military and Space
High Reliability Systems
Voltage Level Shifting

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 66179 has the same components and layout in a 10 pin,
hermetically sealed gull wing package. Figures 1 and 2 from the 66099 Data Sheet illustrate the radiation performance of the
device.
