The ISO7831x device is a high-performance, 3-channel digital isolator with 8000VPK isolation voltage. This device has reinforced isolation certifications according to VDE, CSA, TUV 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. The ISO7831x device has two forward and one reverse-direction channels. If the input power or signal is lost, the default output is high for the ISO7831 device and low for the ISO7831F device. See 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 remarkable chip design and layout techniques, electromagnetic compatibility of ISO7831x has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. ISO7831x is available in a 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.
