The output of the detector is an open collector Schottky clamped transistor. This unique dual coupler design provides maximum DC and AC circuit isolation between each input and output while achieving TTL circuit compatability. The isolator operational parameters are guaranteed from 55C to +125C, such that a minimum input current of 10mA in each channel will sink a six gate fanout (10mA) at the output with 4.5 to 5.5V Vcc applied to the detector. This isolation and coupling is achieved with a typical propagation delay of 60ns. Surface Mount Option Available.

The tPLH propagation delay is measured from the 6.5mA point on the trailing edge of the input pulse to the 1.5V point on the trailing edge of the output pulse. 6. The tPHL propagation delay is measured from the 6.5mA point on the leading edge of the input pulse to the 1.5V point on the leading edge of the output pulse. 7. CMh is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (ie. Vo > 2.0V) 8. CMl is the maximum tolerable common mode transient to assure that the output will remain in a low logic state (ie. Vo < 0.8V) 9. It is essential that a bypass capacitor (0.01 to 0.1F, ceramic) be connected from pin 10 to pin 15. Total lead length between both ends of the capacitor and the isolator pins should not exceed 20mm. 10. This is a momentary withstand test, not an operation condition. Reliability and Approvals Isocom Ltd supplies high reliability devices for applications requiring an operating temperature range of 55C to +125C (e.g. military applications). The 6N134 optocoupler is approved to BS9400 GO123 qualification approval certificate number 0035/G. 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.
