3 Description
The ISO7840x device is a high-performance, quadchannel
digital isolator with a 8000VPK 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. Each
isolation channel has a logic input and output
buffer separated by a silicon-dioxide (SiO2) insulation
barrier.
This device comes with enable pins that can be
used to put the respective outputs in high impedance
for multi-controller driving applications and to reduce
power consumption. The ISO7840 device has four
forward and zero reverse-direction channels. If the
input power or signal is lost, the default output is high
for the ISO7840 device and low for the ISO7840F
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 remarkable chip design and layout
techniques, electromagnetic compatibility of the
ISO7840 device has been significantly enhanced to
ease system-level ESD, EFT, surge, and emissions
compliance.
The ISO7840 device is available in 16-pin SOIC widebody
(DW) and extra-wide body (DWW) packages.
