3 Description
The ISO776x devices are high-performance, sixchannel
digital isolators with 5000-VRMS (DW
package) and 3000-VRMS (DBQ package) isolation
ratings per UL 1577. This family of devices is also
certified according to VDE, CSA, TUV and CQC.
The ISO776x family of devices provides highelectromagnetic
immunity and low emissions at
low-power consumption, while isolating CMOS or
LVCMOS digital I/Os. Each isolation channel has
a logic-input and logic-output buffer separated by
a double capacitive silicon dioxide (SiO2) insulation
barrier. The ISO776x family of devices is available
in all possible pin configurations such that all six
channels are in the same direction, or one, two,
or three channels are in reverse direction while the
remaining channels are in forward direction. 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 family of devices helps prevent noise currents
on data buses, such as RS-485, RS-232, and
CAN , 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
ISO776x family of devices has been significantly
enhanced to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO776x family of devices
is available in 16-pin SOIC and SSOP packages.
