The high speed digital isolators are configured as dual unidirectional in the IL711, and as a bi-directional pair in the IL712. Both devices are integrated with patented* ISOLOOP(R) technology giving them an excellent transient immunity specification. The symmetric magnetic coupling barrier gives these devices a propagation delay of only 10ns and a pulse width distortion of 2 ns. Both the IL711 and the IL712 have 100Mbaud data rates which are independent of direction, i.e. the IL712 operates in full duplex mode making it ideal for many fieldbus bus applications. PROFIBUS / RS485 configurations are achieved by combinations of IL710 and the IL711 or IL712, either combination meeting the overall propagation delay requirements of the specification. Available in 8pin PDIP and 8-pin SOIC packages, the IL711 and IL712 are specified over the temperature range of -40C to +100C without any derating in performance.

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(R) is: I(input)= 40 . f . 1 mA fmax 4 where f= operating frequency fmax= 50 MHz Power Supplies Because the IL711 and IL712 operate internally by using narrow current pulses, it is recommended that low ESR ceramic capacitors be used to decouple the supplies. 47nF capacitors should be placed as close to the device as possible between VDD1 and GND1 as well as between VDD2 and GND2. Signal Status on Start-up and Shut Down To minimize power dissipation, the input signals to the IL711 and IL712 are 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. 1. 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 25OC. 4. CMH is the maximum common mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD. CML is the maximum common mode input voltage that can be sustained while maintaining VO < 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. 4 RHOPOINT COMPONENTS Hurst Green, Oxted, Surrey RH8 9AX UK Telephone: +44 (0) 870 608 1188 Fax: +44 (0) 870 241 2255 Internet: www.rhopointcomponents.com IL711/712 IR Soldering Profile 250 PRE HEATING RATE 3C + 1C /-0.5C /SEC.
