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 reverse-direction 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 devices have been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO774x devices are available in 16-pin SOIC and QSOP packages.

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.

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. 8.2 Functional Block Diagram Transmitter Receiver EN TX IN OOK Modulation TX Signal Conditioning Oscillator SiO2 based Capacitive Isolation Barrier RX Signal Conditioning Envelope Detection RX OUT Emissions Reduction Techniques Copyright © 2016, Texas Instruments Incorporated Figure 19.

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. 24 Submit Documentation Feedback Copyright © 2016–2017, Texas Instruments Incorporated Product Folder Links: ISO7740 ISO7741 ISO7742 ISO7740, ISO7741, ISO7742 www.ti.com SLLSEP4D – MARCH 2016 – REVISED MAY 2017 8.4 Device Functional Modes Table 2 lists the functional modes for the ISO774x devices.

Default mode: When INx is open, the corresponding channel output goes to its default logic state. Default is 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 is 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.

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. 9.2 Typical Application Figure 22 shows the isolated serial peripheral interface (SPI).

Eye Diagram at 100 Mbps PRBS 216 – 1, 2.5 V and 25°C 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 or SN6505A. For such applications, detailed power supply design and transformer selection recommendations are available in SN6501 Transformer Driver for Isolated Power Supplies (SLLSEA0) or SN6505A Low-Noise 1-A Transformer Drivers for Isolated Power Supplies (SLLSEP9). 28 Submit Documentation Feedback Copyright © 2016–2017, Texas Instruments Incorporated Product Folder Links: ISO7740 ISO7741 ISO7742 ISO7740, ISO7741, ISO7742 www.ti.com SLLSEP4D – MARCH 2016 – REVISED MAY 2017 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, refer to the 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. 11.2 Layout Example High-speed traces 10 mils Ground plane 40 mils Keep this space free from planes, traces, pads, and vias FR-4 0r ~ 4.5 Power plane 10 mils Low-speed traces Figure 27.

Reproduction of significant portions of TI information in TI 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 reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all 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. Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection.
