CSM161,
CSM161/L2: Radiation hard device
The CSM160 and CSM161 each consists of four light emitting diodess,
optically coupled to corresponding integrated high gain photon detectors. The
high gain output stages feature open collector outputs providing both lower
output saturation voltage and higher speed of operation than is possible with
conventional photo-darlington type coupler.
The minimum CTR of 300% at an
input current of 0.5 mA makes it ideal for use in low input current applications
such as MOS, CMOS and low power logic interfacing or data transmission systems.
The
CSM160/L2 and CSM161/L2 are subject to 100% high reliability screen.

As manufacturer of high reliability optocouplers Isocom Ltd's manufacturing
plant at North Shields, 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/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.
