Product Overview

The ISO7820FDWW is a high-performance, dual-channel digital isolator with 8000 VPK isolation voltage in 16 pin SOIC package. This device has reinforced isolation certifications according to VDE, CSA, CQC and TUV. It 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 insulation barrier. ISO7820 has two forward channels and no reverse-direction channel. If the input power or signal is lost, default output is 'low' for the ISO7820F device. Used in conjunction with isolated power supplies, it 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 ISO7820 has been significantly enhanced to ease system-level ESD, EFT, surge and emissions compliance.
