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.
