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-Q1 devices also incorporate advanced circuit techniques to maximize the CMTI performance and minimize the radiated emissions due to the high frequency carrier and IO buffer switching. The conceptual block diagram of a digital capacitive isolator, Figure 9-1, shows a functional block diagram of a typical channel. 9.2 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 9-1.

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 ISO774xQ1 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. 26 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated Product Folder Links: ISO7740-Q1 ISO7741-Q1 ISO7742-Q1 ISO7740-Q1, ISO7741-Q1, ISO7742-Q1 www.ti.com SLLSEU0D – NOVEMBER 2016 – REVISED OCTOBER 2020 9.4 Device Functional Modes Table 9-2 lists the functional modes for the ISO774x-Q1 devices.

Default mode: When INx is open, the corresponding channel output goes to its default logic state. Default is High for ISO774x-Q1 and Low for ISO774x-Q1 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-Q1 and Low for ISO774x-Q1 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(2). 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 The outputs are in undetermined state when 1.7 V < VCCI, VCCO < 2.25 V. 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. 10.1 Application Information The ISO774x-Q1 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-Q1 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 Figure 10-1 shows the typical isolated CAN interface implementation.

Eye Diagram at 100 Mbps PRBS 216 – 1, 2.5 V and 25°C 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 10-6 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 10-7 shows the intrinsic capability of the isolation barrier to withstand high voltage stress over its lifetime. Based on the TDDB data, the insulation withstand capability of DW-16 package is 1500 VRMS with a lifetime of 135 years as illustrated in Figure 10-7. Similarly, the insulation withstand capability of DWW-16 package is 2000 VRMS with a corresponding lifetime of 34 years. DBQ-16 package at 400 VRMS working voltage has a much longer lifetime than both DW-16 and DWW-16 packages. Factors, such as package size, pollution degree, and material group can limit the working voltage of a component.

Insulation Lifetime Projection Data 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-Q1 or SN6505B-Q1 . For such applications, detailed power supply design and transformer selection recommendations are available in SN6501-Q1 Transformer Driver for Isolated Power Supplies and SN6505x-Q1 Low-Noise 1-A Transformer Drivers for Isolated Power Supplies data sheets . 32 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated Product Folder Links: ISO7740-Q1 ISO7741-Q1 ISO7742-Q1 ISO7740-Q1, ISO7741-Q1, ISO7742-Q1 www.ti.com SLLSEU0D – NOVEMBER 2016 – REVISED OCTOBER 2020 12 Layout 12.1 Layout Guidelines A minimum of four layers is required to accomplish a low EMI PCB design (see Figure 12-1). Layer stacking should be in the following order (top-to-bottom): high-speed signal layer, ground plane, power plane and lowfrequency 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 highfrequency 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. 12.2 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 12-1.
