The ISO7830x device
is a high-performance, 3-channel digital isolator with 8000-VPK isolation
voltage. This device has reinforced isolation certifications according to VDE, CSA, TUV and CQC.
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 silicon dioxide
(SiO2) insulation barrier. This device 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. The ISO7830x device has three forward and no
reverse-direction channels. If the input power or signal is lost, the default output is
low for the ISO7830 device and high for the ISO7830F device. See Device Functional Modes 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 ISO7830x has
been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance.
ISO7830x is available in a
16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages.
