The IL600 Series are passive input digital signal isolators
with CMOS outputs. They have a similar interface but better
performance and higher package density than optocouplers.

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 various packages, as well
as bare die.

IL600 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).

IL600 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.

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
dV
capacitor current is proportional to input edge speeds ( C 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.

IL600 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.

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.

Approximate Immunity
Immunity Description
A DC current of 16 A flowing in a conductor
1 cm from the device could cause disturbance.
Field applied in H1 direction
±20 Gauss
Field applied in H2 direction
±70 Gauss
A DC current of 56 A flowing in a conductor
1 cm from the device could cause disturbance.
Field applied in any direction but with boost
capacitor (16 pF) in circuit
±250 Gauss
A DC current of 200 A flowing in a conductor
1 cm from the device could cause disturbance.
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 RS-485 and RS-422 Receivers Using IL610s
IL610s can be used as simple isolated RS-485 or RS-422 receivers, terminating signals at
the IL610 for a fraction of the cost of an isolated node. Cabling is simplified by eliminating
the need to power the input side of the receiving board. No current-limiting resistor is
needed for a single receiver because it will draw less current than the driver maximum.
Current limiting resistors allow at least eight nodes without exceeding the maximum load of
the transceiver. Placement of the current-limiting resistors on both lines provides better
dynamic signal balance. There is generally no need for line termination resistors below data
rates of approximately 10 Mbps because the IL610 coil resistance of approximately 85 Ω is
close to the characteristic impedance of most cables. The circuit is intrinsically open-circuit
failsafe because the IL610 is guaranteed to switch to the high state when the coil input
current is less than 0.5 mA.

Low pulse width distortion is critical for CAN bus, and IL600 Isolators are specified for just 3 ns typical pulse width distortion.
Their fail-safe output (logic high output for zero coil current) ensures proper power-on. The speed of IL600 isolators easily
supports the maximum CAN bus transfer speed of 1 Mbps.

used for RS-422/RS-485, LVDS, or other differential networks. The IL610-1 is a unique MSOP isolator when board space is
critical.
