Description
The CH320 is a single channel device in a small outline package suitable for mounting in hybrid sub
assemblies. Electrical contact is made by wire bonding to the thick gold film contacts on the perimeter of
the device.
The device incorporates a high radiance LED and phototransistor.
The isolator operational parameters are guaranteed from -55°C to +125°C
Applications
High Density hybrid sub assemblies, Military high rel. systems, Switch mode power supplies, Medical
instrumentation, System test equipment, Signal transmission between circuit of different potential and
impedance.

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. The
Company is developing a suitable specification to permit release to CECC 20000.
As a manufacturer of high reliability optocouplers Isocom Ltd's manufacturing plant in North East England,
has site approval to BS9000 (registered number 1294/M) 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.
