New from Texas Instruments, the ISO7841 is a high-performance, quad-channel digital isolator with 8000 VPK isolation voltage and reinforced isolation certifications according to VDE, CSA, and CQC. The isolator provides 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. ISO7841 has three forward and one reverse-direction channels. In case of input power or signal loss, default output is 'high'. Used in conjunction with isolated power supplies, the device prevents 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 ISO7841 has been significantly enhanced to ease system-level ESD, EFT, Surge and Emissions compliance. ISO7841 is available in 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.
