The ISO7842 provides galvanic isolation up to 5700 VRMS for 1 minute per UL and 8000 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 ISO7842-EVM helps designers evaluate device performance, supporting the fast development and analysis of isolated systems. The EVM supports evaluation of any of the TI quad-channel digital isolators in a 16-pin SOIC package.
