Isolation
These diode-transistor optocouplers use an insulating layer
between a LED and an integrated
photodetector to provide electrical 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.
