3 Description
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.
