Description

The 6N137, CT2601 optocoupler consist of a 850 nm 

LED, optically coupled to a very high speed integrated 

photo-detector logic gate with a strobable output. This 

output features an open collector, there by permitting 

wired OR outputs. The switching parameters are 

guaranteed over the temperature range of -40°C to 

+85°C. A maximum input signal of 5mA will provide a 

minimum output sink current of 13mA (fan out of 8).

Applications 

• Line receivers 

• Telecommunication equipment 

• Feedback loop in switch-mode power supplies 

• Home appliances

• High speed logic ground isolation
