3 Description
The ISO7810x device is a high-performance, single-
channel digital isolator with 8000 V_PK isolation
voltage. This device has reinforced isolation
certifications according to VDE, CSA, CQC, and TUV.
The isolator provides high electromagnetic immunity
and low emissions at low power consumption, while
isolating CMOS or LVCMOS digital I/Os.
The isolation channel has a logic input and output
buffer separated by silicon dioxide (SiO₂) insulation
barrier. If the input power or signal is lost, the default
output is high for the ISO7810 and low for the
ISO7810F device. See the Device Functional Modes
section 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 the
ISO7810x device has been significantly enhanced to
ease system-level ESD, EFT, surge, and emissions
compliance. The ISO7810x device is available in 16-
pin SOIC wide-body (DW) and extra-wide body
(DWW) packages.The DWW package option comes
with enable pin which can be used to put the output
in high impedance state for multi-master driving
applications and to reduce power consumption.
