This family includes devices with reinforced insulation
ratings according to VDE, CSA, TUV and CQC. The
ISO7731B device is designed for applications that
require basic insulation ratings only.
The ISO773x family of devices provides high
electromagnetic immunity and low emissions at low
power consumption, while isolating CMOS or
LVCMOS digital I/Os. Each isolation channel has a
logic input and output buffer separated by a double
capacitive silicon dioxide (SiO2) insulation barrier.
This device comes with enable pins which can be
used to put the respective outputs in high impedance
for multi-master driving applications and to reduce
power consumption.

5 Description Continued
The ISO7730 device has all three channels in the same direction and the ISO7731 device has two forward and
one reverse-direction channel. If the input power or signal is lost, the default output is high for devices without
suffix F and low for devices with suffix F. See the Device Functional Modes section for further details.
Used in conjunction with isolated power supplies, this family of devices helps prevent noise currents on data
buses, such as RS-485, RS-232, and CAN, or other circuits from entering the local ground and interfering with or
damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility
of the ISO773x device has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions
compliance. The ISO773x family of devices is available in 16-pin wide-SOIC and QSOP packages.

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 in certain cases.
Techniques such as inserting grooves and/or ribs on a printed circuit board are used to help increase these specifications.
This coupler is suitable for safe electrical insulation (ISO773x) and basic electrical insulation (ISO7731B) only within the safety ratings.
Compliance with the safety ratings shall be ensured by means of suitable protective circuits.
Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier.
Apparent charge is electrical discharge caused by a partial discharge (pd).
All pins on each side of the barrier tied together creating a two-terminal device.

7.8 Safety Limiting Values
Safety limiting (1) intends to minimize potential damage to the isolation barrier upon failure of input or output circuitry. A failure
of the I/O 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 maximum safety temperature is the maximum junction temperature specified for the device. The power dissipation and junction-toair thermal impedance of the device installed in the application hardware determines the junction temperature. The assumed junction-toair thermal resistance in the Thermal Information is that of a device installed on a High-K test board for leaded surface mount packages.
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.

9 Detailed Description
9.1 Overview
The ISO773x family of devices has an ON-OFF keying (OOK) modulation scheme to transmit the digital data
across a silicon dioxide based isolation barrier. The transmitter sends a high frequency carrier across the barrier
to represent one digital state and sends no signal to represent the other digital state. The receiver demodulates
the signal after advanced signal conditioning and produces the output through a buffer stage. If the ENx pin is
low then the output goes to high impedance. The ISO773x family of devices also incorporates advanced circuit
techniques to maximize the CMTI performance and minimize the radiated emissions due the high frequency
carrier and IO buffer switching. The conceptual block diagram of a digital capacitive isolator, Figure 17, shows a
functional block diagram of a typical channel.

9.3.1 Electromagnetic Compatibility (EMC) Considerations
Many applications in harsh industrial environment are sensitive to disturbances such as electrostatic discharge
(ESD), electrical fast transient (EFT), surge and electromagnetic emissions. These electromagnetic disturbances
are regulated by international standards such as IEC 61000-4-x and CISPR 22. Although system-level
performance and reliability depends, to a large extent, on the application board design and layout, the ISO773x
family of devices incorporates many chip-level design improvements for overall system robustness. Some of
these improvements include:
• Robust ESD protection cells for input and output signal pins and inter-chip bond pads.
• Low-resistance connectivity of ESD cells to supply and ground pins.
• Enhanced performance of high voltage isolation capacitor for better tolerance of ESD, EFT and surge events.
• Bigger on-chip decoupling capacitors to bypass undesirable high energy signals through a low impedance
path.
• PMOS and NMOS devices isolated from each other by using guard rings to avoid triggering of parasitic
SCRs.
• Reduced common mode currents across the isolation barrier by ensuring purely differential internal operation.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
The ISO773x devices are high-performance, triple-channel digital isolators. These devices come with enable pins
on each side which can be used to put the respective outputs in high impedance for multi-master driving
applications and reduce power consumption. The ISO773x family of devices use single-ended CMOS-logic
switching technology. The voltage range is from 2.25 V to 5.5 V for both supplies, VCC1 and VCC2. When
designing with digital isolators, keep in mind that because of the single-ended design structure, digital isolators
do not conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL
digital signal lines. The isolator is typically placed between the data controller (that is, μC or UART), and a data
converter or a line transceiver, regardless of the interface type or standard.
10.2 Typical Application
The ISO7731 device, combined with Texas Instruments' mixed-signal microcontroller, RS-485 transceiver,
transformer driver, and voltage regulator, can create an isolated RS-485 system as shown in Figure 20.

10.2.3.1 Insulation Lifetime
Insulation lifetime projection data is collected by using industry-standard Time Dependent Dielectric Breakdown
(TDDB) test method. In this test, all pins on each side of the barrier are tied together creating a two-terminal
device and high voltage applied between the two sides; See Figure 26 for TDDB test setup. The insulation
breakdown data is collected at various high voltages switching at 60 Hz over temperature. For reinforced
insulation, VDE standard requires the use of TDDB projection line with failure rate of less than 1 part per million
(ppm). Even though the expected minimum insulation lifetime is 20 years at the specified working isolation
voltage, VDE reinforced certification requires additional safety margin of 20% for working voltage and 87.5% for
lifetime which translates into minimum required insulation lifetime of 37.5 years at a working voltage that's 20%
higher than the specified value.
Figure 27 shows the intrinsic capability of the isolation barrier to withstand high voltage stress over its lifetime.
Based on the TDDB data, the intrinsic capability of the insulation is 1500 VRMS with a lifetime of 135 years. Other
factors, such as package size, pollution degree, material group, etc. can further limit the working voltage of the
component. The working voltage of DW-16 package is specified upto 1500 VRMS and DBQ-16 package up to 400
VRMS. At the lower working voltages, the corresponding insulation lifetime is much longer than 135 years.

11 Power Supply Recommendations
To help ensure reliable operation at data rates and supply voltages, a 0.1-μF bypass capacitor is recommended
at the input and output supply pins (VCC1 and VCC2). The capacitors should be placed as close to the supply pins
as possible. If only a single primary-side power supply is available in an application, isolated power can be
generated for the secondary-side with the help of a transformer driver such as Texas Instruments' SN6501 or
SN6505A. For such applications, detailed power supply design and transformer selection recommendations are
available in the SN6501 Transformer Driver for Isolated Power Supplies data sheet or SN6505A Low-Noise 1-A
Transformer Drivers for Isolated Power Supplies (SLLSEP9).

12 Layout
12.1 Layout Guidelines
A minimum of four layers is required to accomplish a low EMI PCB design (see Figure 28). Layer stacking should
be in the following order (top-to-bottom): high-speed signal layer, ground plane, power plane and low-frequency
signal layer.
• Routing the high-speed traces on the top layer avoids the use of vias (and the introduction of their
inductances) and allows for clean interconnects between the isolator and the transmitter and receiver circuits
of the data link.
• Placing a solid ground plane next to the high-speed signal layer establishes controlled impedance for
transmission line interconnects and provides an excellent low-inductance path for the return current flow.
• Placing the power plane next to the ground plane creates additional high-frequency bypass capacitance of
approximately 100 pF/inch2.
• Routing the slower speed control signals on the bottom layer allows for greater flexibility as these signal links
usually have margin to tolerate discontinuities such as vias.
If an additional supply voltage plane or signal layer is needed, add a second power or ground plane system to
the stack to keep it symmetrical. This makes the stack mechanically stable and prevents it from warping. Also the
power and ground plane of each power system can be placed closer together, thus increasing the high-frequency
bypass capacitance significantly.
For detailed layout recommendations, refer to the Digital Isolator Design Guide.
12.1.1 PCB Material
For digital circuit boards operating below 150 Mbps, (or rise and fall times higher than 1 ns), and trace lengths of
up to 10 inches, use standard FR-4 UL94V-0 printed circuit boards. This PCB is preferred over cheaper
alternatives due to its lower dielectric losses at high frequencies, less moisture absorption, greater strength and
stiffness, and self-extinguishing flammability-characteristics.
