3 Description

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.
