3 Description
The ISO773x devices are high-performance, triple-
channel digital isolators with 5000 V_RMS (DW
package) and 2500 V_RMS (DBQ package) isolation
ratings per UL 1577.
This family of devices has reinforced insulation
ratings according to VDE, CSA, TUV and CQC.
The ISO773x family of devices 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 which can be used to put the
respective outputs in high impedance for multi-master
driving applications and to reduce power
consumption. The ISO7730 device has all three
channels in the same direction and the ISO7731
device has two forward and one reverse-direction
channel. If the input power or signal is lost, the
default output is high for devices without suffix F and
low for devices with suffix F. 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
ISO773x device has been significantly enhanced to
ease system-level ESD, EFT, surge, and emissions
compliance. The ISO773x family of devices is
available in 16-pin wide-SOIC and QSOP packages.
