ISO6740-Q1, ISO6741-Q1, ISO6742-Q1  
SLLSFG4A – AUGUST 2020 – REVISED JANUARY 2021  
ISO674x-Q1 General-Purpose Reinforced Quad-Channel Automotive Digital Isolators  
with Robust EMC  
1 Features  
3 Description  
•
AEC-Q100 qualified with the following results:  
– Device temperature Grade 1: –40°C to +125°C  
ambient operating temperature range  
Meets VDA320 isolation requirements  
50 Mbps data rate  
The ISO674x-Q1 devices are high-performance,  
quad-channel digital isolators ideal for cost-sensitive  
applications requiring up to 5000 VRMS isolation  
ratings per UL 1577. These devices are also certified  
by VDE, TUV, CSA, and CQC.

Robust isolation barrier:  
The  
ISO674x-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 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 ISO6741-Q1  
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.  
– High lifetime at 1060 VRMS working voltage  
– Up to 5000 VRMS isolation rating  
– Up to 10 kV surge capability  
– ±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-Q1) and low  
(ISO674xF-Q1) options  
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 CAN and LIN from damaging sensitive  
circuitry. Through innovative chip design and layout  
techniques, the electromagnetic compatibility of the  
ISO674x-Q1 devices has been significantly enhanced  
to ease system-level ESD, EFT, surge, and emissions  
compliance. The ISO674x-Q1 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.  
•
•
Wide-SOIC (DW-16) Package  
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
