ISO674x General-Purpose Reinforced Quad-Channel Digital Isolators with Robust

EMC

1 Features

3 Description

•

50 Mbps data rate

Robust isolation barrier:

– High lifetime at 1060 V_RMSworking voltage

– Up to 5000 V_RMSisolation rating

– Up to 10 kV surge capability

The ISO674x devices are high-performance, quad-

channel digital isolators ideal for cost-sensitive

applications requiring up to 5000 V_RMSisolation

ratings per UL 1577. These devices are also certified

by VDE, TUV, CSA, and CQC.

The ISO674x 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 TI's double capacitive

silicon dioxide (SiO₂) insulation barrier. These devices

come with enable pins which can be used to put the

respective outputs in high impedance for multi-master

driving applications. The ISO6740 device has all four

channels in the same direction, ISO6741 device has

three forward and one reverse-direction channels, and

ISO6742 device has two forward and two reverse-

direction channels. 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

Device Functional Modes section for further details.

– ±75 kV/μs typical CMTI

Wide supply range: 1.71 V to 1.89 V and 2.25 V to

5.5 V

1.71 V to 5.5 V level translation

Default output high (ISO674x) and low (ISO674xF)

options

Wide temperature range: –40°C to 125°C

1.6 mA per channel typical at 1 Mbps

Low propagation delay: 11 ns typical

Robust electromagnetic compatibility (EMC)

– System-level ESD, EFT, and surge immunity

– ±8 kV IEC 61000-4-2 contact discharge

protection across isolation barrier

– Low emissions

•

Wide-SOIC (DW-16) Package

Used in conjunction with isolated power supplies,

these devices help prevent noise currents on data

buses, such as UART, SPI, RS-485, RS-232, and

CAN from damaging sensitive circuitry. Through

innovative chip design and layout techniques, the

electromagnetic compatibility of the ISO674x devices

has been significantly enhanced to ease system-level

ESD, EFT, surge, and emissions compliance. The

ISO674x family of devices is available in a 16-pin

SOIC wide-body (DW) package and is a pin-to-pin

upgrade to the older generations.

Safety-Related Certifications (pending):

– DIN V VDE 0884-11:2017-01

– UL 1577 component recognition program

– IEC 60950-1, IEC 62368-1, IEC 61010-1,

IEC60601-1 and GB 4943.1-2011 certifications
