Introduction

The ISO7820 is a high-performance dual-channel digital isolator with a high isolation voltage of up to 8000 VPK. This device has passed the enhanced isolation certification compliant with VDE, CSA, and CQC standards. When isolating CMOS or LVCMOS digital I/Os, the isolator provides high electromagnetic immunity, low radiation, and low power consumption. The logic input and output buffers of each isolation channel are separated by a silicon dioxide (SiO₂) insulation barrier. The ISO7820 has two forward channels but no reverse channels. In case of input power or signal loss, the ISO7820 device outputs a default "high" level, while the ISO7820F device outputs a default "low" level. When used with an isolated power supply, this device prevents noise currents on the data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuits. Thanks to the innovative chip design and wiring technology, the electromagnetic compatibility of the ISO7820 is significantly enhanced, ensuring system-level ESD, EFT, and surge protection and compliance with radiation standards. The ISO7820 is available in a 16-pin SOIC wide-body (DW) package.
