Si861x/2x Data Sheet
Low-Power Single and Dual-Channel Digital Isolators
KEY FEATURES
Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering sub-
stantial data rate, propagation delay, power, size, reliability, and external BOM advan-
tages over legacy isolation technologies. The operating parameters of these products
remain stable across wide temperature ranges and throughout device service life for
ease of design and highly uniform performance. All device versions have Schmitt trigger
inputs for high noise immunity and only require VDD bypass capacitors.
• High-speed operation
• DC to 150 Mbps
• No start-up initialization required
• Wide Operating Supply Voltage
• 2.5–5.5 V
• Up to 5000 V
isolation
RMS
Data rates up to 150 Mbps are supported, and all devices achieve propagation delays of
less than 10 ns. Ordering options include a choice of isolation ratings (2.5, 3.75 and 5
kV) and a selectable fail-safe operating mode to control the default output state during
power loss. All products are safety certified by UL, CSA, VDE, and CQC, and products
• Reinforced VDE 0884-10, 10 kV surge-
capable (Si862xxT)
• 60-year life at rated working voltage
• High electromagnetic immunity
• Ultra low power (typical)
in wide-body packages support reinforced insulation withstanding up to 5 kVRMS
.
Automotive Grade is available for certain part numbers. These products are built using
automotive-specific flows at all steps in the manufacturing process to ensure the robust-
ness and low defectivity required for automotive applications.
