16 - Anode 1 - Cathode |
7 - GND 8 - Vo 9 - BASE (CSM810/811 NOT CONNECTED) 10 - Vcc |
Hermetically sealed 16 pad leadless chip carrier
High speed; Typ. 700
kbit/s (NRZ)
1500 Vdc withstand test voltage
4N55 function compatible
Logic compatible
Performance guaranteed over -55°C to +125°C
ambient temperature range
CSM801/811, 15% <= CTR <= 22%
CSM810/811, base not connected for
improved noise immunity
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.

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.
