Isolation

Description

These diode-transistor optocoup-

lers use an insulating layer

between a LED and an integrated

photodetector to provide elec-

trical 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 conven-

tional phototransistor coupler by

reducing the base-collector

capacitance.
