3 Description

The ISO773x devices are high-performance, triple-

channel

digital

isolators

with

5000

ratings per UL 1577.

This family of devices has reinforced insulation

ratings according to VDE, CSA, TUV and CQC.

The

ISO773x

family

of

devices

provides

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

with enable pins which can be used to put the

respective outputs in high impedance for multi-master

driving

applications

and

to

reduce

power

consumption. The ISO7730 device has all three

channels in the same direction and the ISO7731

device has two forward and one reverse-direction

channel. 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

device helps 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,

electromagnetic

compatibility

of

the

ISO773x device has been significantly enhanced to

ease system-level ESD, EFT, surge, and emissions

compliance. The ISO773x family of devices is

available in 16-pin wide-SOIC and QSOP packages.
