HIGH VOLTAGE DARLINGTON

OUTPUT OPTICALLY COUPLED

ISOLATOR

APPROVALS

l UL recognised, File No. E91231

DESCRIPTION

The IS66_ series are optically coupled isolators
consisting of infrared light emitting diode and a
high voltage NPN silicon photo darlington which
has an integral base-emitter resistor to optimise
switching speed and elevated temperature
characteristics in a standard 6pin dual in line
plastic package.
