DESCRIPTION
The IS4N45, IS4N46 are optically coupled
isolators consisting of an infrared light emitting
diode and a 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. These devices are designed to
equal the 4N45, 4N46 characteristics while
providing greater voltage and current capability.
