The ISO7142CCDBQ is a quad-channel Digital Isolator with noise filter. It provides galvanic isolation up to 2500-VRMS for 1 minute per UL and 4242VPK per VDE. The ISO7142CC comes with the two forward and two reverse-direction channels. It is capable of maximum data rate of 50Mbps with 5V supplies and 40Mbps with 3.3 or 2.7V supplies. It has integrated filters on the inputs to support noise-prone applications. Each isolation channel has 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 circuits from entering the local ground and interfering with or damaging sensitive circuitry. This device has TTL input thresholds.
50Mbps Maximum signalling rate
