Description  
These diode-transistor optocouplers  
use an insulating layer between a  
LED and an integrated

insulation between input and  
output. Separate connections for  
the photodiode bias and output-  
transistor collector increase the  
speed up to a hundred times that of  
a conventional phototransistor  
coupler by reducing the base-  
collector capacitance.
