3 Description
The ISO7840x device is a high-performance, quad-
channel digital isolator with a 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/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-master 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 innovative 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
wide-body (DW) and extra-wide body (DWW)
packages.
