Description
NVE’s IL700 family of high-speed digital isolators are CMOS devices
manufactured with NVE’s patented* spintronic Giant Magnetoresistive
(GMR) technology. 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.

Notes (apply to both 3.3 V and 5 V specifications):
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 PWD divided by pulse width.
3. tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH between devices at 25°C.
4. CMH and CML are the maximum common mode voltage slew rates that can be applied with the outputs remaining stable and within VOL and
VOH specifications.
5. Device is considered a two terminal device: pins 1–4 shorted and pins 5–8 shorted.
6. Dynamic power consumption is calculated per channel and is supplied by the channel’s input side power supply.
7. Minimum pulse width is the minimum value at which specified PWD is guaranteed.
8. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 9.
9. External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin” (see diagram on p. 9).

Figure 4. 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.

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.

Figure 2. Isolated CAN circuit.
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.
