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.

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.

Maximum case temperature SOIC-8  
°C  
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.

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
