The ISO7710-Q1 device is a high-performance,
single-channel digital isolator with 5000
VRMS (DW package) and 3000
VRMS (D package) isolation ratings per
UL 1577. This device is also certified by VDE,
TUV, CSA, and CQC.The ISO7710-Q1 device provides high
electromagnetic immunity and low emissions at low
power consumption, while isolating CMOS or LVCMOS
digital I/Os. The isolation channel has a logic
input and output buffer separated by a double
capacitive silicon dioxide (SiO2)
insulation barrier. In the event of input power or
signal loss, default output is high for a
device without suffix F and low for a
device with suffix F. See the Device Functional Modes section for
further details. Used in conjunction with isolated power supplies,
the device helps prevent noise currents on data
buses, such as CAN and LIN, or
other circuits from entering the local ground and
interfering with or damaging sensitive circuitry.
Through innovative chip design and layout
techniques, the electromagnetic compatibility of
the ISO7710-Q1 device has been significantly
enhanced to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO7710-Q1
device is available in 16-pin SOIC wide-body (DW)
and 8-pin SOIC narrow-body (D) packages.
