3 Description
The ISO7810 is a high-performance, single-channel
digital isolator with 8000 V_PK isolation voltage. This
device has reinforced isolation certifications
according to VDE, CSA, and CQC. The isolator
provides high electromagnetic immunity and low
emissions at low power consumption, while isolating
CMOS or LVCMOS digital I/O’s. Each isolation
channel has a logic input and output buffer separated
by silicon dioxide (SiO₂) insulation barrier. If the input
power or signal is lost, default output is 'high' for the
ISO7810 and 'low' for the ISO7810F device. See
Device Functional Modes for further details. Used in
conjunction with isolated power supplies, this device
prevents 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 ISO7810 has been
significantly enhanced to ease system-level ESD,
EFT, Surge and Emissions compliance. ISO7810 is
available in 16-pin SOIC wide-body (DW) package.
