ISO6760L Six-Channel Reinforced Digital Isolators with Integrated Interlock and
Robust EMC
1 Features
3 Description
•
ISO6760 with integrated Interlock function
– Designed to support opposite polarity of
adjacent channels
– Three sets of paired interlock channels
Robust isolation barrier:
– High lifetime at 1500 VRMS working voltage
– Up to 5000 VRMS isolation rating
– Up to 10 kV surge capability
– ±130 kV/μs typical CMTI
Wide supply range: 1.71 V to 1.89 V and 2.25 V to
5.5 V
Channel output non-inverting (ISO6760L) and
inverting (ISO6760LN) options
50 Mbps data rate
The ISO6760L and ISO6760LN devices are high-
performance, six-channel digital isolators with
integrated interlock function for applications requiring
up to 5000 VRMS isolation ratings per UL 1577. These
devices are also certified by VDE, TUV, CSA, and
CQC.
•
The ISO6760L family of devices integrate a series of
logic gates to provide hardware interlock functionality
for adjacent channels. The interlock feature ensures
that each channel, in a channel pairing, will not be
enabled at the same time. If both channels in the
pairing share the same input logic, the output logic will
always be low. The ISO6760L family of devices have
all six channels in the same direction and 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.

1.71 V to 5.5 V level translation
Wide temperature range: –40°C to 125°C
1.4 mA per channel typical at 1 Mbps
Robust electromagnetic compatibility (EMC)
– System-level ESD, EFT, and surge immunity
– Low emissions
Used in conjunction with intelligent power modules
(IPMs), the interlock feature in these devices help
prevent shoot through current between the high
side and low side gate driver during turn on
and turn off events. Six channels, including three
pairings of interlock circuitry, are integrated in a
16-pin SOIC wide-body (DW) package with space
savings greater than 50% compared to optocoupler
solutions. Through innovative chip design and layout
techniques, the electromagnetic compatibility of the
ISO6760L devices has been significantly enhanced to
ease system-level ESD, EFT, surge, and emissions
compliance.
