The IL711S and IL712S are the world's fastest two-channel isolators, with a 150 Mbps typical data rate for both channels. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion as low as 300 ps (0.3 ns), achieving the best specifications of any isolator. Typical transient immunity of 30 kV/s is unsurpassed. The IL711 has two transmit channels; the IL712 and IL721 have one transmit and one receive channel. The IL712 and IL721 operate full duplex, making them ideal for many fieldbus applications, including PROFIBUS, DeviceNet, and CAN. The IL721 has channels reversed to better suit certain board layouts. The IL711 and IL712 are available in 8-pin MSOP, SOIC, and PDIP packages. The IL721 is available in an 8-pin SOIC package. Standard and S-Grade parts are specified over a temperature range of -40C to +100C; T-Grade parts have a maximum operating temperature of +125C.

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. Both power supplies to these devices should be decoupled with low-ESR 47 nF ceramic capacitors. Ground planes for both GND1 and GND2 are highly recommended for data rates above 10 Mbps. Capacitors must be located as close as possible to the VDD pins. Signal Status on Start-up and Shut Down Electromagnetic Compatibility To minimize power dissipation, input signals 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. Unless the circuit connected to the isolator performs its own poweron reset (POR), the designer should consider including an initialization signal in the start-up circuit. Initialization consists of toggling the input either high then low, or low then high. In CAN applications, the IL712 or IL721 should be used with CAN transceivers with Dominant Timeout functions for seamless POR. IsoLoop Isolators have the lowest EMC footprint of any isolation technology. IsoLoop Isolators' Wheatstone bridge configuration and differential magnetic field signaling ensure excellent EMC performance against all relevant standards. These isolators are fully compliant with generic EMC standards EN50081, EN50082-1 and the umbrella line-voltage standard for Information Technology Equipment (ITE) EN61000. NVE has completed compliance tests in the categories below: Most CAN transceiver manufacturers offer Dominant Timeout options. Examples include NXP's TJA 1050 and TJA 1040 transceivers. EN50081-1 Residential, Commercial & Light Industrial Methods EN55022, EN55014 EN50082-2: Industrial Environment Methods EN61000-4-2 (ESD), EN61000-4-3 (Electromagnetic Field Immunity), EN61000-4-4 (Electrical Transient Immunity), EN61000-4-6 (RFI Immunity), EN61000-4-8 (Power Frequency Magnetic Field Immunity), EN61000-4-9 (Pulsed Magnetic Field), EN61000-4-10 (Damped Oscillatory Magnetic Field) ENV50204 Radiated Field from Digital Telephones (Immunity Test) Data Transmission Rates The reliability of a transmission system is directly related to the accuracy and quality of the transmitted digital information. For a digital system, those parameters which determine the limits of the data transmission are pulse width distortion and propagation delay skew. Propagation delay is the time taken for the signal to travel through the device. This is usually different when sending a low-to-high than when sending a high-to-low signal. This difference, or error, is called pulse width distortion (PWD) and is usually in nanoseconds. It may also be expressed as a percentage: Immunity to external magnetic fields is even higher if the field direction is "end-to-end" rather than to "pin-to-pin" as shown in the diagram below: PWD% = Maximum Pulse Width Distortion (ns) Signal Pulse Width (ns) x 100% For example, with data rates of 12.5 Mbps: PWD% = 3 ns x 100% = 3.75% 80 ns Cross-axis Field Direction This figure is almost three times better than any available optocoupler with the same temperature range, and two times better than any optocoupler regardless of published temperature range. IsoLoop isolators exceed the 10% maximum PWD recommended by PROFIBUS, and will run to nearly 35 Mb within the 10% limit. Dynamic Power Consumption IsoLoop Isolators achieve their low power consumption from the way 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 2.5 ns, the power consumption is independent of mark-to-space ratio and solely dependent on frequency. This has obvious advantages over optocouplers, which have power consumption heavily dependent on mark-to-space ratio. Propagation delay skew is the signal propagation difference between two or more channels. This becomes significant in clocked systems because it is undesirable for the clock pulse to arrive before the data has settled. Short propagation delay skew is therefore especially critical in high data rate parallel systems for establishing and maintaining accuracy and repeatability. Worstcase channel-to-channel skew in an IL700 Isolator is only 3 ns, which is ten times better than any optocoupler. IL700 Isolators have a maximum propagation delay skew of 6 ns, which is five times better than any optocoupler. 6 IL711/IL712/IL721 Illustrative Applications Isolated CAN 3 ADR 0...7, CS Tx0 TxD 1 XTAL1 Rx0 RxD 4 7 CANH 6 CANL XTAL2 TJA1050 IL712/IL721 2 SJA1000 In today's CAN networks, node-to-node isolation is increasingly recommended by designers to reduce EMI susceptibility, especially in highspeed applications and in hybrid and electrical vehicle networks, where the 12 V battery has been replaced with one of several hundred volts. Operator and equipment safety becomes critical when a high voltage source, such as the battery, needs to be connected to diagnosis systems during routine maintenance procedures. In the application shown above, the microcontroller is isolated from the CAN transceiver by an IL712 or IL721, allowing higher speed and more reliable bus operation by eliminating ground loops and reducing susceptibility to noise and EMI events. The best-in-class 10 ns typical IL712/IL721 propagation delay minimizes CAN loop delay and maximizes data rate over any given bus length. The simple circuit works with any CAN transceiver with a TxD dominant timeout, which includes all of the current-generation transceivers.
