DESCRIPTION
The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are oriented
in the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic input
and output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to
4000 V. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and
prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or
damaging sensitive circuitry.
A binary input signal is conditioned, translated to a balanced signal, then differentiated by the capacitive isolation
barrier. Across the isolation barrier, a differential comparator receives the logic transition information, then sets or
resets a flip-flop and the output circuit accordingly. A periodic update pulse is sent across the barrier to ensure
the proper dc level of the output. If this dc-refresh pulse is not received every 4 µs, the input is assumed to be
unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state.
The small capacitance and resulting time constant provide fast operation with signaling rates available from 0
Mbps (dc) to 150 Mbps. (1)The A-, B- and C-option devices have TTL input thresholds and a noise filter at the
input that prevents transient pulses from being passed to the output of the device. The M-option devices have
CMOS VCC/2 input thresholds and do not have the input noise-filter and the additional propagation delay.
These devices require two supply voltages of 3.3 V, 5 V, or any combination. All inputs are 5-V tolerant when
supplied from a 3.3-V supply and all outputs are 4-mA CMOS.
These devices are characterized for operation over the ambient temperature range of –40°C to 125°C.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

NOTE: Creepage and clearance requirements should be applied according to the specific equipment isolation
standards of an application. Care should be taken to maintain the creepage and clearance distance of a board
design to ensure that the mounting pads of the isolator on the printed circuit board do not reduce this distance.
Creepage and clearance on a printed circuit board become equal according to the measurement techniques
shown in the Isolation Glossary. Techniques such as inserting grooves and/or ribs on a printed circuit board are
used to help increase these specifications.

IEC SAFETY LIMITING VALUES
Safety limiting intends to prevent potential damage to the isolation barrier upon failure of input or output circuitry.
A failure of the IO can allow low resistance to ground or the supply and, without current limiting, dissipate
sufficient power to overheat the die and damage the isolation barrier potentially leading to secondary system
failures.

The safety-limiting constraint is the absolute maximum junction temperature specified in the absolute maximum
ratings table. The power dissipation and junction-to-air thermal impedance of the device installed in the
application hardware determines the junction temperature. The assumed junction-to-air thermal resistance in the
Thermal Characteristics table is that of a device installed in the JESD51-3, Low Effective Thermal Conductivity
Test Board for Leaded Surface Mount Packages and is conservative. The power is the recommended maximum
input voltage times the current. The junction temperature is then the ambient temperature plus the power times
the junction-to-air thermal resistance.

ISOLATION GLOSSARY
Creepage Distance — The shortest path between two conductive input to output leads measured along the
surface of the insulation. The shortest distance path is found around the end of the package body.
Clearance — The shortest distance between two conductive input to output leads measured through air (line of
sight).
Input-to Output Barrier Capacitance — The total capacitance between all input terminals connected together,
and all output terminals connected together.
Input-to Output Barrier Resistance — The total resistance between all input terminals connected together, and
all output terminals connected together.
Primary Circuit — An internal circuit directly connected to an external supply mains or other equivalent source
which supplies the primary circuit electric power.
Secondary Circuit — A circuit with no direct connection to primary power, and derives its power from a separate
isolated source.
Comparative Tracking Index (CTI) — CTI is an index used for electrical insulating materials which is defined as
the numerical value of the voltage which causes failure by tracking during standard testing. Tracking is the
process that produces a partially conducting path of localized deterioration on or through the surface of an
insulating material as a result of the action of electric discharges on or close to an insulation surface -- the higher
CTI value of the insulating material, the smaller the minimum creepage distance.
Generally, insulation breakdown occurs either through the material, over its surface, or both. Surface failure may
arise from flashover or from the progressive degradation of the insulation surface by small localized sparks. Such
sparks are the result of the breaking of a surface film of conducting contaminant on the insulation. The resulting
break in the leakage current produces an overvoltage at the site of the discontinuity, and an electric spark is
generated. These sparks often cause carbonization on insulation material and lead to a carbon track between
points of different potential. This process is known as tracking.

Insulation:
Operational insulation — Insulation needed for the correct operation of the equipment.
Basic insulation — Insulation to provide basic protection against electric shock.
Supplementary insulation — Independent insulation applied in addition to basic insulation in order to ensure
protection against electric shock in the event of a failure of the basic insulation.
Double insulation — Insulation comprising both basic and supplementary insulation.
Reinforced insulation — A single insulation system which provides a degree of protection against electric shock
equivalent to double insulation.
Pollution Degree:
Pollution Degree 1 — No pollution, or only dry, nonconductive pollution occurs. The pollution has no influence.
Pollution Degree 2 — Normally, only nonconductive pollution occurs. However, a temporary conductivity caused
by condensation must be expected.
Pollution Degree 3 — Conductive pollution occurs or dry nonconductive pollution occurs which becomes
conductive due to condensation which is to be expected.
Pollution Degree 4 – Continuous conductivity occurs due to conductive dust, rain, or other wet conditions.
Installation Category:
Overvoltage Category — This section is directed at insulation co-ordination by identifying the transient
overvoltages which may occur, and by assigning 4 different levels as indicated in IEC 60664.
I: Signal Level — Special equipment or parts of equipment.
II: Local Level — Portable equipment etc.
III: Distribution Level — Fixed installation
IV: Primary Supply Level — Overhead lines, cable systems
Each category should be subject to smaller transients than the category above.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
