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.

(1) 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.
(2) 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.
(3) Testing is carried out in air to determine the surge immunity of the package
(4) Testing is carried out in oil to determine the intrinsic surge immunity of the isolation barrier.
(5) Apparent charge is electrical discharge caused by a partial discharge (pd).
(6) 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 junction-to-air thermal resistance, RθJA, in the table is that of a device installed on a high-K test board for leaded surface-mount
packages. Use these equations to calculate the value for each parameter:
TJ = TA + RθJA × P, where P is the power dissipated in the device.
TJ(max) = TS = TA + RθJA × PS, where TJ(max) is the maximum allowed junction temperature.
PS = IS × VI, where VI is the maximum input voltage.

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, 图 9-1, 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
备注
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 图10-1.

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 图 10-7 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 50% for
lifetime which translates into minimum required insulation lifetime of 30 years at a working voltage that's 20%
higher than the specified value.
图 10-8 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 169 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 169 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 图 12-1). 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.
