The ISO7821 is a high-performance, dual-channel digital isolator with 8000 VPK isolation voltage. This device has reinforced isolation certifications according to VDE, CSA, CQC, and TUV. The isolator provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/O’s. Each isolation channel has a logic input and output buffer separated by silicon dioxide SiO2 insulation barrier. ISO7821 has one forward and one reverse-direction channel. If the input power or signal is lost, default output is ’high’ for the ISO7821 and ’low’ for the ISO7821F device. Used in conjunction with isolated power supplies, this 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 ISO7821 has been significantly enhanced to ease system-level ESD, EFT, Surge and Emissions compliance. ISO7821 is available in 16-pin SOIC wide-body DW and extra-wide body DWW packages. The DWW package option 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.
