Description 

The CTW137 optocouplers consist of a 850 nm 

AlGaAS 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). 

The device is packaged in an 8-pin DIP wide body 

and also available in surface mount option.
