ISO7821FDWWR Information

General Description

The ISO7821FDWWR offers versatility and reliability, with one forward and one reverse-direction channel to suit a variety of system configurations. In the event of input power or signal loss, the default output is 'high' for the ISO7821 and 'low' for the ISO7821F device, providing a fail-safe mechanism for your system. By using isolated power supplies alongside this device, you can effectively prevent noise currents from entering sensitive circuitry and causing interference or damage. The ISO7821FDWWR's innovative chip design and layout techniques have significantly enhanced its electromagnetic compatibility, easing system-level ESD, EFT, Surge, and Emissions compliance. With package options including the 16-pin SOIC wide-body (DW) and extra-wide body (DWW) options, the ISO7821FDWWR caters to diverse application requirements. Furthermore, the DWW package option comes with enable pins to put the outputs in high impedance for multi-master driving applications and reduce power consumption, providing added flexibility and efficiency for your system
