Description
The IL600A-Series are isolated signal couplers with opendrain outputs. They have a similar interface but better
performance and higher package density than optocouplers.
The devices are manufactured with NVE’s patented*
IsoLoop® spintronic Giant Magnetoresistive (GMR)
technology for small size, high speed, and low power.
A unique ceramic/polymer composite barrier provides
excellent isolation and virtually unlimited barrier life.
A resistor sets the input current; a capacitor in parallel with
the current-limit resistor provides improved dynamic
performance.
These versatile components simplify inventory requirements
by replacing a variety of optocouplers, functioning over a
wide range of data rates, edge speeds, and power supply
levels. The devices are available in MSOP, SOIC, and PDIP
packages, as well as bare die.

IL600A Series Isolators
Applications Information
IL600-Series Isolators are current mode devices. Changes in current flow into the input coil result in logic state changes at the
output. As shown in Figure 1, output logic high is the zero input current state.
Coil Polarity
3.5
The device switches to logic low if current flows from (In−) to (In+).
Note that the designations “In−“ and “In+” refer to logic levels, not
current flow. Positive values of current mean current flow into
the In− input.

Figure 1. Typical IL600-Series Transfer Function
Resistors set the coil input current (see Figure 2). There is no limit to
input voltages because there are no semiconductor input structures.
Worst-case logic low threshold current is 8 mA, which is for singleended operation with a 3 V supply. In differential mode, where the
input current reverses, the logic low threshold current is 5 mA for the
range of supplies. A “boost capacitor” creates current reversals at edge
transitions, reducing the input logic low threshold current to the
differential level of 5 mA.
Typical Resistor Values
The table shows typical
values for the external
resistor for 5 mA coil
current. The values are
approximate and should be adjusted for temperature or other
application specifics. If the expected temperature range is large, 1%
tolerance resistors may provide additional design margin.

Single-Ended or Differential Input
The IL610, IL611, IL613, and channel 1 of the IL614 can be run with
single-ended or differential inputs (see Test Circuits on page 5). In the
differential mode, current will naturally flow through the coil in both
directions without a boost capacitor, although the capacitor can still be
used for increased external field immunity or improved PWD.
VINL
Figure 2. Limiting Resistor Calculation
Equivalent Circuit
Absolute Maximum recommended coil current in single-ended mode
is 25 mA while differential mode allows up to ±75 mA to flow. The
difference in specifications is due to the risk of electromigration of
coil metals under constant current flow. In single ended mode, long-term DC current flow above 25 mA can cause erosion of the
coil metal. In differential mode, erosion takes place in both directions as each current cycle reverses and has a net effect of zero up
to the absolute maximum current.
An advantage over optocouplers and other high-speed couplers in differential mode is that no reverse bias protection for the input
structure is required for a differential signal.
One of the more common applications is for an isolated Differential Line Receiver. For example, RS-485 can drive an IL610
directly for a fraction of the cost of an isolated RS-485 node (see Illustrative Applications).

IL600A Series Isolators
Non-inverting and Inverting Configurations
IL600-Series Isolators can be configured in noninverting and inverting configurations (see Figure
3). In a typical non-inverting circuit, the In−
terminal is connected via a 1 kΩ input resistor to
the supply rail, and the input is connected to the In+
terminal. The supply voltage is +5 V and the input
signal is a 5 V CMOS signal. When a logic high
(+5 V) is applied to the input, the current through
the coil is zero. When the input is a logic low (0 V),
at least 5 mA flows through the coil from the In−
side to the In+ side.
The inverting configuration is similar to standard
logic. In the inverting configuration, the signal into
the coil is differential with respect to ground. The
designer must ensure that the difference between
the logic low voltage and the coil ground is such
that the residual coil current is less than 0.5 mA.

The IL612 and IL614 devices have some inputs
that do not offer inverting operation. The IL612
coil In− input is hardwired internally to the device
power supply; therefore it is important to ensure the
isolator power supply is at the same voltage as the
power supply to the source of the input logic signal.
The IL614 has a common coil In− for two inputs.
This pin should be connected to the power supply
for the logic driving channels 2 and 3, and the
channels run should be run in non-inverting mode.
Both single ended and differential inputs can be
handled without reverse bias protection.

The boost capacitor in parallel with the current-limiting resistor boosts the instantaneous coil current at the signal transition. This
ensures switching and reduces propagation delay and reduces pulse-width distortion.

Select the value of the boost capacitor based on the rise and fall
times of the signal driving the inputs. The instantaneous boost
capacitor current is proportional to input edge speeds ( C dV
dt ). Select a
capacitor value based on the rise and fall times of the input signal to be
isolated that provides approximately 20 mA of additional “boost”
current. Figure 4 is a guide to boost capacitor selection. For high-speed
logic signals (tr,tf < 10 ns), a 16 pF capacitor is recommended. The
capacitor value is generally not critical; if in doubt, choose a higher
value.

IL600A Series Isolators
Dynamic Power Consumption
Power consumption is proportional to duty cycle, not data rate. The use of NRZ coding minimizes power dissipation since no
additional power is consumed when the output is in the high state. In differential mode, where the logic high condition may still
require a current to be forced through the coil, power consumption will be higher than a typical NRZ single ended configuration.
Power Supply Decoupling
47 nF low-ESR ceramic capacitors are recommended to decouple the power supplies. The capacitors should be placed as close as
possible to the appropriate VDD pin.
Maintaining Creepage
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.
Electromagnetic Compatibility and Magnetic Field Immunity
Because IL600-Series Isolators are completely static, they have the lowest emitted noise of any non-optical isolators.
IsoLoop Isolators operate by imposing a magnetic field on a GMR sensor, which translates the change in field into a change in
logic state. A magnetic shield and a Wheatstone Bridge configuration provide good immunity to external magnetic fields.
Immunity to external magnetic fields can be enhanced by proper orientation of the device with respect to the field direction, the
use of differential signaling, and boost capacitors.
1. Orientation of the device with respect to the field direction
An applied field in the “H1” direction is the worst case for
magnetic immunity. In this case the external field is in the same
direction as the applied internal field. In one direction it will
tend to help switching; in the other it will hinder switching.
This can cause unpredictable operation.
NC
VDD
IN+

An applied field in direction “H2” has considerably less effect
and results in higher magnetic immunity.

2. Differential Signaling and Boost Capacitors
Regardless of orientation, driving the coil differentially improves magnetic immunity. This is because the logic high state is driven
by an applied field instead of zero field, as is the case with single-ended operation. The higher the coil current, the higher the
internal field, and the higher the immunity to external fields. Optimal magnetic immunity is achieved by adding the boost
capacitor.

Data Rate and Magnetic Field Immunity
It is easier to disrupt an isolated DC signal with an external magnetic field than it is to disrupt an isolated AC signal. Similarly, a
DC magnetic field will have a greater effect on the device than an AC magnetic field of the same effective magnitude. For
example, signals with pulses longer than 100 μs are more susceptible to magnetic fields than shorter pulse widths.

Isolated 120V Line Monitor
The wide input voltage range of IL600 Isolators allows connection to line voltage through current-limiting resistors. Unlike
optocouplers, input voltage can reverse without damaging the inputs. In this illustrative circuit, “Monitor Out” goes low when
line voltage drops significantly. The 74HC123 monostable converts the 60 Hz isolator output to a monitor signal.

Multi-channel Isolated Alarm Monitor
The open-drain outputs of IL600A-Series Isolators allow wired-OR outputs. The inputs can be configured for inverting or noninverting operation (see Applications Information), and a very wide input voltage range is possible. This illustrative circuit
provides fail-safe output (logic high output for zero coil current) and typical logic output sink current of 10 mA for each
isolator.
