ISO7142CC provides galvanic isolation up to 2500-VRMS for 1 minute
per UL and 4242-VPK 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.
