ISO776x High-speed, robust EMC, reinforced six-channel digital isolators
1 Features
1 100 Mbps data rate
• Robust isolation barrier:
– >100-Year projected lifetime
– Up to 5000 VRMS isolation rating
– Up to 12.8 kV surge capability
– ±100 kV/μs Typical CMTI
• Wide supply range: 2.25 V to 5.5 V
• 2.25-V to 5.5-V Level translation
• Default output high (ISO776x) and low
(ISO776xF) Options
• Wide temperature range: –55°C to +125°C
• Low power consumption, typical 1.4 mA per
channel at 1 Mbps
• Low propagation delay: 11 ns typical at 5 V
• 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
• Wide-SOIC (DW-16) and SSOP (DBQ-16)
package options
• Automotive version available: ISO776x-Q1
• Safety-related certifications:
– Reinforced insulation per DIN V VDE V 0884-
11:2017-01
– UL 1577 component recognition program
– CSA Certification per IEC 60950-1, IEC 62368-
1, and IEC 60601-1
– CQC Certification per GB4943.1-2011
– TUV Certification according to EN 60950-1 and
EN 61010-1
The ISO776x family of devices provides 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 logic-output buffer separated by a
double capacitive silicon dioxide (SiO2) insulation
barrier. The ISO776x family of devices is available in
all possible pin configurations such that all six
channels are in the same direction, or one, two, or
three channels are in reverse direction while the
remaining channels are in forward direction. If the
input power or signal is lost, the default output is high
for devices without suffix F and low for devices with
suffix F. See the Device Functional Modes section for
further details.
Used in conjunction with isolated power supplies, this
family of devices helps prevent noise currents on
data buses, such as RS-485, RS-232, and CAN, or
other circuits from entering the local ground and
interfering with or damaging sensitive circuitry.
Through innovative chip design and layout
techniques, electromagnetic compatibility of the
ISO776x family of devices has been significantly
enhanced to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO776x family of
devices is available in 16-pin SOIC and SSOP
packages.
