66293 PROTON RADIATION TOLERANT SINGLE/DUAL CHANNEL, LOW-INPUT CURRENT, OPTOCOUPLER (Electrically similar to 6N140) MICROPAC OPTOELECTRONIC PRODUCTS DIVISION 07/20/2006 Features: Applications: • • • • • • • • • Proton Radiation Tolerant High current transfer ratio: 750% typical 1500 Vdc isolation test voltage Low input current requirement: 1.6 mA Telephone ring detection Voltage level shifting Isolated receiver input Communication systems Medical systems DESCRIPTION The 66293 single/dual optocoupler utilizes an 850 nm infrared LED with proven tolerance to proton radiation optically coupled to a high gain photodarlington detector. This unique optocoupler provides high CTR and low leakage current over the full military temperature range (-55° to +125°C). The 66293 is an 8 pin dual-in-line, hermetically sealed package and is available in standard and screened versions or tested to customer specifications.

Derate IF at 0.1 mA/°C above 25°C. Collector output power plus one half of the total supply power is total output power. Derate at 0.5 mW/°C above 25°C. The lowest total IOH over temperature is developed by keeping VCC as low as possible, but greater that 2 Volts. The most negative voltage at the detector side should be applied to Pin 5.

Each channel. 2. CURRENT TRANSFER RATIO is defined as the ratio of output collector current, IO, to the forward LED input current., IF , times 100%. 3. IF = 2 µA for channel under test. For all other channels, IF = 10 mA. 4. Device considered a two-terminal device. 5. Measured between each input pair shorted together and all output pins shorted together. 6. Measured between each input pair shorted together. 7. CMH is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (i.e. VO > 2.0 V). 7,9 8,9 8. CML is the maximum tolerable common mode transient to assure that the output will remain in a low logic state (i.e. VO < 0.8 V). 9. In applications where dV/dt may exceed 50,000 V/µs (such as static discharge) a series resistor, RCC , should be included to protect the detector IC’s from 1V destructively high surge currents. The recommended value is RCC = kΩ. 0.60 IF(mA) MICROPAC INDUSTRIES, INC.
