The ISO7142CC-Q1 device provides galvanic isolation up to
2500 VRMS for 1 minute per UL 1577 and 4242-VPK per
VDE V 0884-10. The
ISO7142CC-Q1 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. The ISO7142CC-Q1
device 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.
For all available packages, see the orderable addendum at the
end of the data sheet.
