3 Description
The ISO772x-Q1 devices are high-performance, dual-
channel digital isolators with 5000 V_RMS (DW
package) and 3000 V_RMS (D package) isolation
ratings per UL 1577. These devices are also certified
by VDE, TUV, CSA, and CQC.
The ISO772x-Q1 devices provide 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. The ISO7720-Q1
device has both channels in the same direction while
the -Q1 device has both channels in the opposite
direction. In the event of input power or signal loss,
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,
these devices help 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, the electromagnetic compatibility of the
ISO772x-Q1 devices has been significantly enhanced
to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO772x-Q1 family of
devices is available in 16-pin SOIC wide-body (DW)
and 8-pin SOIC narrow-body (D) packages.
