ISO7142CC - 4242-Vpk Small Footprint and Low-Power 2/2 Quad Channel Digital Isolator with Noise Filter

ISO7142CC provides galvanic isolation up to 2500-V_RMS for 1 minute per UL and 4242-V_PK per VDE. ISO7142CC is a quad-channel isolator with two forward and two reverse-direction channels. This device is capable of maximum data rate of 50 Mbps with 5-V supplies and 40 Mbps with 3.3-V or 2.7-V supplies. ISO7142CC 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 and can operate from 2.7-V, 3.3-V, and 5-V supplies.
