Each channel is composed of a Gallium Arsenide infra-red emitting diode and a high gain photon detector. The high gain output stage features and open collector output providing both lower output saturation and higher speed of operation than is possible with conventional photodarlington type couplers. The CH390 series are being used in environments encounted by space applications. It is manufactured to meet the JANS standard in conjunction with MIL-PRF-19500 procedures (please see next page for all other applicable specifications). Package styles for this device include 5 Pin Hybrid Package with surface mount, solder dip option available. These packages have a shield effect to cut off ambient light as they are designed for high density mounting applications. Therefore absolute maximum ratings, recommended operating conditions, electrical specifications and performance characteristics are identical for all units. Any exceptions, due to packaging variations and limitations, are as noted.

The ground pin 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. Input pins are shorted together, and output pins are shorted together. 8. Measured between the LED anode and cathode shorted together and pins at output shorted together. 9. Measured between adjacent input pairs shorted together. 10. CMH is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (i.e., VO > 2.0V). 11. CML is the maximum tolerable common mode transient to assure that the output will remain in the logic low state (i.e., VO< 0.8V). 12. In applications where dV/dt may exceed 50,000V/µS (such as a static discharge), a series resistor, RCC, should be included to protect the detector IC’s from destructively high surge currents. The recommended value is RCC = 1V kΩ 0.6IF(mA) 13. This is a momentary withstand test, not an operating condition.
