DESCRIPTION
These devices are single, dual and quad optocouplers.
Each channel is composed of a Gallium Arsenide infra-
red emitting diode and a silicon phototransistor.
Package styles for these devices include 4pin, 8 pin, and
16 pin, 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 above 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 Darlingtons 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
Performance guaranteed over -55°C to +125°C temperature range
Manufactured and tested in BS9000 and CECC20000 approved premises
High current transfer ratio
5000V electrical isolation
