Hermetically sealed 8 pin ceramic dual in line package
High speed; Typ. 700 kbit/s (NRZ)
1500 Vdc withstand test voltage
High radiation immunity
Performance guaranteed over -55°C to +125°C ambient temperature range
4N55 function compatible
CS801/811, 15% <= CTR <= 22% at 25°C
CS810/811, base not connected for improved noise immunity
The CS800 series are single channel devices hermetically sealed in 8 pin
They incorporate a GaAsP LED 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 16mA: 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. Surface Mount Option Available.

Isocom Ltd supplies high reliability devices for applications requiring an
operating temperature range of -55°C to +125°C (e.g. military
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.
