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.
ABSOLUTE MAXIMUM RATINGS
Peak Forward Input Current (each channel) (1 ms duration)...............................................................................................20 mA
Average Forward Input Current (each channel) (Note 1) ....................................................................................................10 mA
Reverse Input Voltage ..............................................................................................................................................................5 V
Output Current - I_O (each channel) .....................................................................................................................................40 mA
Output Power Dissipation (each channel) (Note 2) ........................................................................................................... 50 mW
Supply Voltage - V_CC (Note 3)....................................................................................................................................... 0.5 to 20 V
Output Voltage - V_O (each channel) (Note 3) ............................................................................................................ -0.5 to 20 V
Storage Temperature........................................................................................................................................... -65°C to +150°C
Operating Free-Air Temperature Range.............................................................................................................. -55°C to +125°C
Lead Solder Temperature (10 seconds, 1/16” below seating plane)................................................................................... 260°C
Notes:
1. Derate I_F at 0.1 mA/°C above 25°C.
2. Collector output power plus one half of the total supply power is total output power. Derate at 0.5 mW/°C above 25°C.
3. The lowest total I_OH over temperature is developed by keeping V_CC as low as possible, but greater that 2 Volts. The most
negative voltage at the detector side should be applied to Pin 5.
