3 Description
The ISO7820 is a high-performance, dual-channel
digital isolator with 8000 VPK 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/O’s. Each isolation
channel has a logic input and output buffer separated
by silicon dioxide (SiO2) insulation barrier. ISO7820
has two forward channels and no reverse-direction
channel. If the input power or signal is lost, default
output is 'high' for the ISO7820 and 'low' for the
ISO7820F device. 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 ISO7820
has been significantly enhanced to ease system-level
ESD, EFT, Surge and Emissions compliance.
ISO7820 is available in 16-pin SOIC wide-body (DW)
and extra-wide body (DWW) packages. The DWW
package option 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.
