OPTOELECTRONIC PRODUCTS
DIVISION
REVISION A 7/14/00
Features:
• Current transfer ratio: 150% typical
• Base lead provided for conventional transistor
biasing
• Low power consumption
• High radiation immunity
• 1000 Vdc isolation test voltage
Applications:
• Military and Space
• High Reliability Systems
• Voltage Level Shifting
• Isolated Receiver Inputs
• Communication Systems
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
