3 Description

The ISO7831x device is a high-performance, 3-

channel

digital

isolator

with

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

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.
