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.
