Absolute Maximum ambient operating temperature means the device will not be damaged if operated under these conditions. It does not guarantee performance. 2. PWD is defined as | tPHL -tPLH |. %PWD is equal to the PWD divided by the pulse width. 3. tPSK is equal to the magnitude of the worst case difference in tPHL and/or tPLH that will be seen between units at 25 O 4. CM H is the maximum common mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD 2.C ML is the maximum common mode input voltage that can be sustained while maintaining V O < 0.8 V . The common mode voltage slew rates apply to both rising and falling common mode voltage edges. 5. Device is considered a two terminal device: pins 1-4 shorted and pins 5-8 shorted. Application Notes: Power Consumption Isoloop devices achieve their low power consumption from the manner by which they transmit data across the isolation barrier. By detecting the edge transitions of the input logic signal and converting these to narrow current pulses a magnetic field is created around the GMR Wheatstone bridge. Depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal. Since the current pulses are narrow, about 2.5ns wide, the power consumption is independent of mark-to-space ratio and solely dependent on frequency. This has obvious advantages over optocouplers whose power consumption is heavily dependent on its on-state and frequency. The approximate power supply current per channel for Isoloop ® is: I(input)= 40 . f . 1 mA fmax 4 where f= operating frequency fmax= 50 MHz Power Supplies It is recommended that low ESR ceramic capacitors be used to decouple the supplies. 10nF capacitors should be placed as close to the device as possible between V DD 1 and GND 1,as well as between VDD 2 and GND 2. Signal Status on Start-up and Shut Down To minimize power dissipation, the input signal to the IL710 is differentiated and then latched on the output side of the isolation barrier to reconstruct the signal. This could result in an ambiguous output state depending on power up, shutdown and power loss sequencing. Therefore, the designer should consider the inclusion of an initialization signal in his start-up circuit. Electrostatic Discharge Sensitivity This product has been tested for electrostatic sensitivity to the limits stated in the specifications. However, NVE recommends that all integrated circuits be handled with appropriate care to avoid damage. Damage caused by inappropriate handling or storage could range from performance degradation to complete failure.
