3 Description
The ISO7831x device is a high-performance, 3-
channel digital isolator with 8000-VPK isolation
voltage. This device has reinforced isolation
certifications according to VDE, CSA, TUV and CQC.
The isolator provides high electromagnetic immunity
and low emissions at low power consumption, while
isolating CMOS or LVCMOS digital I/Os.
Each isolation channel has a logic input and output
buffer separated by silicon dioxide (SiO2) insulation
barrier. This device comes with enable pins which
can be used to put the respective outputs in high
impedance for multi-master driving applications and
to reduce power consumption. The ISO7831x device
has two forward and one reverse-direction channels.
If the input power or signal is lost, the default output
is high for the ISO7831 device and low for the
ISO7831F device. See Device Functional Modes for
further details.
Used in conjunction with isolated power supplies, this
device helps prevent noise currents on a data bus or
other circuits from entering the local ground and
interfering with or damaging sensitive circuitry.
Through innovative chip design and layout
techniques, electromagnetic compatibility of
ISO7831x has been significantly enhanced to ease
system-level ESD, EFT, surge, and emissions
compliance. ISO7831x is available in a 16-pin SOIC
wide-body (DW) and extra-wide body (DWW)
packages.
