CS800
High Speed
Hermetically Sealed
Ceramic Optocoupler
ISOCOM®LTD
Isocom Ltd supplies high reliability devices for
applications requiring an operating temperature
range of -55°C to +125°C.
Devices supplied have completed rigorous testing,
and various high reliability test options are offered.
As manufacturer of high reliability optocouplers
Isocom Ltd's manufacturing plant at North Shields,
England, has site approval to BS9OOO (registered
number 1294/M) and CECC2OOOO (registered
number M/1084/CECC/UK) issued by the British
Standards Institution.
Together with CECC, BS9OOO is a preferred
standard for use in European military projects.
Consequently, Isocom Ltd's approved devices are
listed in the CECC "MUAHAG" preferred products
list.
The BS9000 approval is also recognised as meeting
the equivalent criteria to those required by
BS5750/IS09000/EN29000.
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.

Description
The CS800 series are single channel devices hermetically sealed ceramic packages.
They incorporate a GaAsP L.E.D. emitter and integrated photon detector.
CS800/810 High speed, TTL compatible optocouplers.
CS801/811 High speed, TTL compatible optocouplers for use in applications requiring matched or known
CTR.
At l6mA: 15%≤CTR≤22%
The CS810 and CS811 are provided with the output transistor base not connected for greater immunity to noise
and reduced ESD susceptibility.
Parts designated /L2 are subject to 100% high reliability screening.
