The CH350 is a single channel device sealed in a small outline ceramic
package suitable for mounting in hybrid sub-assemblies. It incorporates a high
radiance LED and a high gain integrated photodetector. The output is an open
collector Schottky clamped transistor.
The isolator operational parameters are guaranteed from -55°C to 125°C.
Military, high reliability system, telephone ring detection, microprocessor system interface, level shifting, digital logic ground isolation, current loop receiver, system test equipment isolation, process control input/output isolation.

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.
