ISO674x General-Purpose Quad-Channel Digital Isolators with Robust EMC
1 Features
3 Description
•
•
50 Mbps data rate
Robust isolation barrier:
– High lifetime at 1060 VRMS working voltage
– Up to 5000 VRMS isolation 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
isolation
RMS
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. ISO6741 device has three
forward and one 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.

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

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.
