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 Power Dissipation (each channel) (Note 2) ........................................................................................................... 50 mW

Storage Temperature........................................................................................................................................... -65°C to +150°C

Operating Free-Air Temperature Range.............................................................................................................. -55°C to +125°C

Notes:

1.

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.

negative voltage at the detector side should be applied to Pin 5.
