Description
The CSM800 series are single channel devices hermetically sealed in 16 pad ceramic packages.
They incorporate a GaAlAs LED emitter and integrated photon detector.
CSM800/810 High speed, TTL compatible optocouplers.
CSM801/811 High speed, TTL compatible optocouplers for use in applications requiring matched or known CTR. At 16mA: 15% <=
CTR <= 22%
The CSM810 and CSM811 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.

Reliability and Approvals
Isocom Ltd supplies high reliability devices for applications requiring an operating temperature range of -55°C to +125°C (e.g.
military applications).
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 East England, has site approval to BS9000
(registered number 1294/M) and CECC20000 (registered number M/1084/CECC/UK) issued by the British Standards Institution.
Together with CECC, BS9000 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/ISO9000/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.
Isocom takes great effort to ensure accurate data, but regrettably cannot be held liable for any error on its website. Visit File Lists to
