High-Immunity, 5.7kVRMS Reinforced Quad-Channel 2/2 Digital Isolator Evaluation Module


Order now


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.

  • 8000 VPK isolation per VDE0884-10 Ed 2.0
  • 5.7 kVRMS isolation for 1 minute per UL 1577
  • Signaling rate: 100 Mbps
  • Isolation barrier life: > 25 years
