1 / 50 page  ISO674x-Q1 Automotive, General-Purpose, Reinforced, Quad-Channel Digital Isolators With Robust EMC 1 Features • Functional Safety-Capable – Documentation available to aid functional safety system design: ISO6740-Q1, ISO6741-Q1, ISO6742-Q1 • AEC-Q100 qualified with the following results: – Device temperature Grade 1: –40°C to 125°C ambient operating temperature range • Meets VDA320 isolation requirements • 50Mbps data rate • Robust isolation barrier: – High lifetime at 1500VRMS working voltage – Up to 5000VRMS isolation rating – Up to 10kV surge capability – ±150kV/μs typical CMTI • Wide supply range: 1.71V to 1.89V and 2.25V to 5.5V • 1.71V to 5.5V level translation • Default output high (ISO674x-Q1) and low (ISO674xF-Q1) options • 1.6mA per channel typical at 1Mbps • Low propagation delay: 11ns typical • Robust electromagnetic compatibility (EMC) – System-level ESD, EFT, and surge immunity – ±8kV IEC 61000-4-2 contact discharge protection across isolation barrier – Low emissions • Wide-SOIC (DW-16) Package • Safety-Related Certifications : – DIN EN IEC 60747-17 (VDE 0884-17) – UL 1577 component recognition program – IEC 62368-1, IEC 61010-1, IEC 60601-1 – GB 4943.1 2 Applications • Hybrid, electric and power train system (EV/HEV) – Battery management system (BMS) – On-board charger – DC/DC converter – Inverter and motor control 3 Description The ISO674x-Q1 devices are high-performance, quad-channel digital isolators designed for cost- sensitive applications requiring up to 5000VRMS isolation ratings per UL 1577. These devices are also certified by VDE, TUV, CSA, and CQC. The ISO674x-Q1 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 TI's double capacitive silicon dioxide (SiO2) insulation barrier. These devices come with enable pins which can be used to put the respective outputs in high impedance for multi-controller driving applications. The ISO6740-Q1 device has all four channels in the same direction, the ISO6741-Q1 device has three forward and one reverse-direction channels, and the ISO6742-Q1 device has two forward and two reverse- direction channels. In the event of input power or signal loss, the default output is high for devices without suffix F and low for devices with suffix F. See also Device Functional Modes section. Used in conjunction with isolated power supplies, the ISO674x-Q1 devices help prevent noise currents on data buses, such as CAN and LIN from damaging sensitive circuitry. Through remarkable chip design and layout techniques, the electromagnetic compatibility of the ISO674x-Q1 devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO674x- Q1 family of devices is available in a 16-pin SOIC wide-body (DW) package and is a pin-to-pin upgrade to the older generations. ISO6740-Q1, ISO6741-Q1, ISO6742-Q1 SLLSFG4F – DECEMBER 2019 – REVISED JUNE 2024 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
