The ISO7140FCCDBQ is a quad-channel Digital Isolator provides galvanic isolation up to 2500VRMS for 1 minute per UL and 4242VPK per VDE. It has three channels with two forward and one reverse-direction channels. It is capable of 50Mbps maximum data rate with 5V supplies and 40Mbps maximum data rate with 3.3 or 2.7V supplies, with integrated filters on the inputs for noise-prone applications. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
