The CS700 consists of an IR light emitting diode, optically coupled to a corresponding integrated high gain photon detector. The high gain output stage features an open collector output providing both lower output saturation voltage and higher speed of operation than possible with a conventional photodarlington type coupler. The minimum CTR of 200% at an input current of 0.5mA makes it ideal for use in low input current applications such as MOS, CMOS and low power logic interfacing or data transmission systems. Surface Mount Option Available.
Military, high reliability system, telephone ring detection, microprocessor system interface, level shifting, digital logic ground isolation, current loop receiver, isolation input line receiver, system test equipment isolation, process control input/output isolation

1. Pin 5 should be the most negative voltage at the detector side. Keeping
Vcc as low as possible, but greater than 2.0V, will provide lowest total Ioh
over temperature.
2. Output Power is collector output power.
3. Current
Transfer Ratio is defined as the ratio of output collector current Io to the
forward LED input current If, times 100%.
4. Pins 1 through 4 shorted
together and pins 5 through 8 shorted together.
5. This is a momentary
withstand test, not an operation condition.
6. CMh is the maximum tolerable
common mode transient to assure that the output will remain in a high logic
state (ie. Vo > 2.0V)
7. CMl is the maximum tolerable common mode
transient to assure that the output will remain in a low logic state (ie. Vo <
0.8V)
8. In applications where dV/dt may exceed 50000V/µs (such as
static a discharge), a series resistor Rcc should be included to protect the
detector ICs from destructively high surge currents. The recommended value is
Rcc=(1
V) / (0.6 If mA) kohm.
9. Measured between the LED anode and cathode shorted
together and pins 5,6,7,8 shorted together.
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.
