3 Description

The

ISO774x-Q1

devices

are

high-performance,

ratings per UL 1577. This family of devices has

reinforced insulation ratings according to VDE, CSA,

TUV and CQC.

The ISO774x-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 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 ISO7740-Q1 device has all four

channels in the same direction, the ISO7741-Q1

device has three forward and one reverse-direction

channels, and the ISO7742-Q1 device has two

forward and two reverse-direction channels. If the

input power or signal is lost, 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

ISO774x-Q1

devices

have

been

significantly

enhanced to ease system-level ESD, EFT, surge, and

emissions compliance. The ISO774x-Q1 devices are

available in 16-pin SOIC and QSOP packages.
