Withstand Test Voltage
The 6N140A consists of four IR light emitting diodes, each 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 operation than possible with a conventional photodarlington type coupler. The minimum CTR of 300% 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.

transient upset
1. Pin 10 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 plus one fourth of
total supply power. Derate at 1.66mW/°C above 110°C.
3. Derate If
at 0.33mA/°C above 110°C.
4. Each channel.
5. Current Transfer
Ratio is defined as the ratio of output collector current Io to the forward LED
input current If, times 100%.
6. Iohx is the leakage current resulting from
channel to channel optical crosstalk. If=2µA for channel under test. For
all other channels, If=10mA.
7. Pins 1 through 8 shorted together and pins 9
through 16 shorted together.
8. Measured between LED anode and cathode
shorted together and pins 10 through 15 shorted together.
9. Measured
between adjacent input pairs shorted together (ie. pins 1 and 2 shorted
together, and pins 3 and 4 shorted together, etc.)
10. CMh is the maximum
tolerable common mode transient to assure that the output will remain in a high
logic state (ie. Vo > 2.0V)
11. CMl is the maximum tolerable common mode
transient to assure that the output will remain in a low logic state (ie. Vo < 0.8V)
12. 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.
13. This is a momentary withstand test, not an
operation condition.
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.
