3 Description
The ISO774x devices are high-performance, quadchannel digital isolators with 5000 VRMS (DW
package) and 2500 VRMS (DBQ package) isolation
ratings per UL 1577. This family of devices has
reinforced insulation ratings according to VDE, CSA,
TUV and CQC.
The ISO774x devices provide 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 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. The ISO7740
device has all four channels in the same direction, the
ISO7741 device has three forward and one reversedirection channels, and the ISO7742 device has two
forward and two reverse-direction channels. If the
input power or signal is lost, 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
device helps prevent noise currents on a data bus 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
ISO774x family of devices has been significantly
enhanced to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO774x family of
devices is available in 16-pin 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 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.

6.8 Safety Limiting Values
Safety limiting 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-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 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

8 Detailed Description
8.1 Overview
The ISO774x family of devices have 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 ISO774x devices also incorporate 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 19, shows a functional
block diagram of a typical channel.

8.3.1 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 ISO774x
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.

COMMENTS
Normal Operation:
A channel output assumes the logic state of its input.
Default mode: When INx is open, the corresponding channel output
goes to its default logic state. Default= High for ISO774x and Low for
ISO774x with F suffix.
A low value of output enable causes the outputs to be highimpedance.
Default mode: When VCCI is unpowered, a channel output assumes
the logic state based on the selected default option. Default= High for
ISO774x and Low for ISO774x with F suffix.
When VCCI transitions from unpowered to powered-up, a channel
output assumes the logic state of the input.
When VCCI transitions from powered-up to unpowered, channel output
assumes the selected default state.
When VCCO is unpowered, a channel output is undetermined (3).
When VCCO transitions from unpowered to powered-up, a channel
output assumes the logic state of the input.
VCCI = Input-side VCC; VCCO = Output-side VCC; PU = Powered up (VCC ≥ 2.25 V); PD = Powered down (VCC ≤ 1.7 V); X = Irrelevant; H
= High level; L = Low level ; Z = High Impedance
A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output.
The outputs are in undetermined state when 1.7 V < VCCI, VCCO < 2.25 V.

9 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.
9.1 Application Information
The ISO774x devices are high-performance, quad-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 ISO774x 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 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. For
such applications, detailed power supply design and transformer selection recommendations are available in
SN6501 data sheet (SLLSEA0).

11 Layout
11.1 Layout Guidelines
A minimum of four layers is required to accomplish a low EMI PCB design (see Figure 27). 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, see application note, Digital Isolator Design Guide (SLLA284).
11.1.1 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.

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)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
