A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL711S and IL712S are the world’s fastest two-channel isolators, with a 150 Mbps typical data rate for both channels. Standard and S-Grade parts are specified over a temperature range of −40°C to +100°C; “T” and “V” Grade parts have a maximum operating temperature of 125°C. V- Grade versions offer extremely high isolation voltages of 6 kVRMS for wide-body packages and 2.5 kVRMS for MSOPs. 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. Minimum transient immunity of 100 kV/µs is unsurpassed. The IL711 has two transmit channels; the IL712 and IL721 have one transmit and one receive channel. 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 IL711 and IL721 are also available in NVE’s unique JEDECcompliant 16 pin package with True 8 mm creepage under IEC 60601.

IL711 / IL712 / IL721 equivalent circuit (each channel). Isolator Signal Path The GMR isolator signal path starts with a buffered input signal that is driven through an ultraminiature coil. This generates a small magnetic field that changes the electron spin polarization of GMR resistors, which are configured as a Wheatstone bridge. The change in spin polarization of the resistors creates a bridge voltage which drives an output comparator to construct an isolated version of the input signal. Small Size, High Speed, and Low EMI The coil, GMR, and circuitry are integrated to allow small packages. GMR is inherently high speed and low distortion, and unlike transformers, does not rely on energy transfer, so power is low and EMI emissions are minimal. High Magnetic Immunity GMR provides large signals which improve magnetic immunity, and the Wheatstone bridge configuration cancels ambient common-mode magnetic fields, further enhancing immunity to external magnetic fields. 10 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 (952) 829-9217 www.nve.com YouTube.com/NveCorporation iso-apps@nve.com IL711/IL712/IL721 Electrostatic Discharge Sensitivity Power Supply Decoupling 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. Both power supplies should be decoupled with 0.1 µF typical (0.047 µF minimum) capacitors as close as possible to the VDD pins. Ground planes for both GND1 and GND2 are highly recommended for data rates above 10 Mbps. Maintaining Creepage Electromagnetic Compatibility 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. Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used, should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet. These isolators are fully compliant with IEC 61000-6-1 and IEC 61000-6-2 standards for immunity, and IEC 61000-6-3, IEC 61000-6-4, CISPR, and FCC Class A standards for emissions. Signal Status on Start-up and Shut Down 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 power- on reset (POR), a start-up initialization circuit should be considered. Initialization consists of toggling the input either high then low, or low then high. 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: Cross-axis Field Direction In CAN applications, the IL712 or IL721 should be used with CAN transceivers with Dominant Timeout functions for seamless POR. Most CAN transceivers have Dominant Timeout options. Examples include NXP’s TJA 1050 and TJA 1040 transceivers. 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. 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 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: PWD% = Maximum Pulse Width Distortion (ns) x 100% Signal Pulse Width (ns) For example, with data rates of 12.5 Mbps: PWD% = 3 ns x 100% = 3.75% 80 ns 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. 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. Propagation delay skew is especially critical in high data rate parallel systems for establishing and maintaining accuracy and repeatability. Worst-case channel-to-channel skew in an IL700 Isolator is just 3 ns— ten times better than any optocoupler. IL700 Isolators have a maximum propagation delay skew of 6 ns— five times better than any optocoupler. 11 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 (952) 829-9217 www.nve.com YouTube.com/NveCorporation iso-apps@nve.com IL711/IL712/IL721 Illustrative Applications NVE offers a unique line of single-chip isolated RS-485, PROFIBUS, and CAN transceivers, but as illustrated in the circuits below, IL700-Series Isolators can also be used as part of multi-chip designs with non-isolated transceivers: Isolation Boundary 1 8 2 7 3 6 4 5 RS-485 Truth Table D DE 1 0 0 0 1 1 0 1 8 4 IL711 A Z Z 1 0 B Z Z 0 1 R X X 1 0 3 5 4 6 3 7 2 1 8 1 2 6 7 5 IL710 ISL8485 Figure 1.

CAN isolation is increasingly necessary to reduce EMI susceptibility, especially in high- speed 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. This simple circuit works with any CAN transceiver with a TxD dominant timeout, which includes all of the current-generation transceivers.
