3 Description

The ISO7830x device is a high-performance, 3-

channel digital isolator with 8000V

PK

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 (SiO

2

) 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 Section 7.4 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 remarkable 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.
