ISO672x-Q1 General Purpose Reinforced and Basic Dual-Channel Digital Isolators
with Robust EMC
1 Features

•
50-Mbps data rate
Robust isolation barrier:
The ISO672x-Q1 devices are high-performance, dual-
channel digital isolators ideal for cost sensitive
applications requiring up to 5000 VRMS (DWV
package) and 3000 VRMS (D package) isolation
ratings per UL 1577. These devices are also certified
by VDE, TUV, CSA, and CQC.
– High lifetime at 1060 VRMS working voltage
– Up to 5000 VRMS isolation rating
– ±75 kV/μs typical CMTI
Wide supply range: 1.71 V to 1.89 V and 2.25 V to
5.5 V

The
ISO672x-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. The
ISO6720-Q1 device has both channels in the same

Low propagation delay: 11 ns typical
AEC-Q100 qualified with the following results:
– Device temperature Grade 1: –40°C to +125°C
ambient operating temperature range
Meets VDA320 isolation requirements
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

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, IEC
60601-1 and GB 4943.1-2011 certifications
direction. ISO6721-Q1 device has
2
isolation
channels with 1 channel in each direction. 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.

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
ISO672x-Q1 devices has been significantly enhanced
to ease system-level ESD, EFT, surge, and emissions
compliance.
