3 Description

The ISO7830x 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 ISO7830x device

has three forward and no reverse-direction channels.

If the input power or signal is lost, the default output

is high for the ISO7830 device and low for the

ISO7830F 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

ISO7830x has been significantly enhanced to ease

system-level ESD, EFT, surge, and emissions

compliance. ISO7830x is available in a 16-pin SOIC

wide-body (DW) and extra-wide body (DWW)

packages.
