The ISO7342C provides galvanic isolation up to 3000 VRMS for 1 minute per UL and 4242 VPK per VDE. This device has four isolated channels comprised of a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry.
The ISO7342CEVM helps designers evaluate device performance, supporting the fast development and analysis of isolated systems. The EVM supports evaluation of any of the TI ISO73xx triple- or quad-channel Digital Isolators in a 16DW package.
