Product details
Overview
SI8463AA-B-IS1 from Skyworks Solutions is a six-channel, ultra-low-power digital isolator in a 16-pin narrow-body SOIC package, supporting up to 150 Mbps data rate with worst-case propagation delay <9.5 ns, 0.5 ns channel-channel skew, and 25 kV/µs common-mode transient immunity. It operates across 2.70–5.5 V supply rails and delivers <17.2 mA per side at 100 Mbps (5 V), enabling high-speed isolated communication in motor control and industrial power inverters.
For engineers reviewing the SI8463AA-B-IS1 datasheet, SI8463AA-B-IS1 pinout, SI8463AA-B-IS1 application, or SI8463AA-B-IS1 equivalent, key selection criteria include its 150 Mbps capability, 2.5 kVrms reinforced isolation rating, precise timing (1.5 ns pulse width distortion), and compatibility with 2.7–5.5 V dual supplies - critical for isolated ADC interfaces and HEV battery management systems.
Technical Context
The SI8463AA-B-IS1 implements capacitive digital isolation using on-chip RF modulation/demodulation across a silicon dioxide barrier, eliminating magnetic coupling and startup initialization. Its six independent bidirectional channels support asymmetric configuration (e.g., 4:2 or 3:3) with separate VDD1/VDD2 domains.
It achieves stable timing performance over –40°C to +125°C at full 150 Mbps, with output impedance ~85 Ω ±40% and controlled-impedance PCB trace termination recommended. Safety certification includes UL 1577 (2500 VRMS), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (reinforced insulation).

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM140D0BRZ | Four-channel, 150 Mbps, 2.5 kVrms, SOIC-16; higher 22 mA supply current at 100 Mbps (5 V). | Limited to four channels; requires two devices for six-signal isolation, increasing board area and BOM count. | Select when four-channel count suffices and ADI ecosystem integration is prioritized. |
| ISO6760QDWR | Six-channel, 100 Mbps, 5000 VRMS, SOIC-16; wider 1.71–5.5 V supply range but lower speed. | Higher isolation rating suits medical/AES applications, but 100 Mbps limit restricts use in >20 kHz PWM systems. | Select when 5 kVRMS is mandatory and data rate ≤100 Mbps satisfies control loop requirements. |
Compared with ADUM140D0BRZ and ISO6760QDWR, SI8463AA-B-IS1 uniquely balances six-channel count, 150 Mbps speed, and ultra-low power (17.2 mA @100 Mbps), making it optimal for space-constrained, high-bandwidth industrial inverters where thermal budget and channel density are critical.

FAQ
What is the maximum data rate supported by the SI8463AA-B-IS1?
The SI8463AA-B-IS1 supports a maximum data rate of 150 Mbps under specified conditions (VDD = 5 V, TA = –40°C to +125°C). This is confirmed in Table 3 and Table 4 of the Skyworks datasheet Rev. 1.6 for the Si846xBx variant, which SI8463AA-B-IS1 belongs to. The device maintains this rate with worst-case propagation delay ≤9.5 ns and pulse width distortion ≤2.5 ns.
Does the SI8463AA-B-IS1 require external components for startup or biasing?
No, the SI8463AA-B-IS1 requires no start-up initialization and operates immediately upon power application. Only VDD bypass capacitors (recommended 100 nF ceramic per supply) are needed - no external resistors, level shifters, or timing components. This is explicitly stated in the "Features" section and verified in Section 2.3 ("Device Operation") of the datasheet.
What safety certifications apply to the SI8463AA-B-IS1?
The SI8463AA-B-IS1 is certified to UL 1577 (2500 VRMS, File E257455), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (File 5006301-4880-0001). These cover reinforced insulation up to 300 VRMS working voltage (CSA) and 560 Vpeak (VDE), with production testing to 3000 VRMS for 1 second per Table 6.
How does the power consumption of SI8463AA-B-IS1 compare at different supply voltages?
At 100 Mbps, SI8463AA-B-IS1 draws 17.2 mA per side at 5 V, 12.7 mA per side at 3.3 V, and 10.5 mA per side at 2.7 V (Table 3–5). This scalable current enables optimization for low-noise analog domains (3.3 V) or legacy 5 V systems without sacrificing speed - a key advantage over fixed-voltage isolators.
Can SI8463AA-B-IS1 be used in automotive applications?
Yes - SI8463AA-B-IS1 is qualified for operation from –40°C to +125°C at full 150 Mbps and supports 60-year lifetime at rated working voltage, aligning with AEC-Q100 stress test expectations. While not AEC-Q100 certified out-of-box, its design and reliability data make it suitable for non-safety-critical HEV subsystems like battery monitoring and HVAC inverter control, per Skyworks' application guidance.
