DESCRIPTION
These devices are dual channel optocouplers. Each channel is composed of a Gallium Arsenide infra-red
emitting diode and a darlington phototransistor. Package styles for these devices are 8 pin dil with surface
mount, butt cut and gull wing options available.
The same electrical die, assembly processes and materials are used for each channel of each device shown
below. Therefore absolute maximum ratings, recommended operating conditions, electrical specifications and
performance characteristics are identical for all units. Any exceptions, due to packaging variations and
limitations, are as noted.
Isocom Ltd supplies a multitude of plastic
optocouplers for all applications varying from
standard transistor optos through to Darlington and
Schmitt Trigger devices. It’s massive family of optos
vary in speed allowing maximum opportunity to
engineers worldwide.
All devices are performance guaranteed between -
20ºC and +80ºC and have completed rigorous testing.
The Company's customers can be assured of our
commitment to stringent quality, reliability and
inspection standards, as demonstrated by our existing
approvals. Other customer specific options can also be
offered.
FEATURES
