DESCRIPTION
The ISP815 is an optically coupled isolator. It consists of a Gallium Arsenide infrared emitting diode and a
NPN silicon photo-darlington transistor mounted in a standard 4 pin dual-in-line package
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.
