3 Description

The ISO772x-Q1 devices are high-performance, dual-

channel

digital

isolators

with

5000

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

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.
