66191

66191 PROTON RADIATION TOLERANT OPTOCOUPLER (Single Channel, Electrical EQUIVALENT TO 66099) Mii 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 ABSOLUTE MAXIMUM RATINGS (ta = 25°C unless otherwise noted) Storage Temperature..........................................................................................................................................-55°C to +150°C Operating Free-Air Temperature Range.............................................................................................................-55°C to +100°C Lead Solder Temperature (10 seconds max)......................................................................................................................240°C Input to output Isolation Voltage.........(see Note 1).......
